Research Summary

We seek to identify molecules that act during the pre-commitment period to cause the commitment event of terminal differentiation in murine erythroleukemia cells (MELC). We mutagenized MELC by retroviral insertion and isolated mutants that fail to commit to the terminal erythrodifferentiation program. Repeatedly, and independently, one particular genomic locus was the insertional target in fail-to-commit mutants. We now seek to identify the gene associated with this locus. We identified a novel mammalian protein kinase, which we termed STPK13, whose mRNA declines dramatically during the MELC pre-commitment period. Further investigation demonstrated that the mRNA also fluctuates in abundance during the normal cell cycle. Homologous genes, termed polo and cdc5 have recently been isolated from Drosophila and Saccharomyces cerevisiae, respectively. Analyses of mutants of these genes have revealed a requirement during mitosis for the encoded protein kinase. The cell cycle-associated mRNA fluctuations we observed in mouse cells is conserved in S. cerevisiae and thus has been maintained during at least five hundred million years of evolution; it is expected to be a fundamental mechanism of regulation of the protein kinase. Our recent observations suggest that cell cycle-associated regulation of pre-mRNA splicing plays a central role in the cell cycle-associated fluctuation of the abundance of this mRNA. The decline in STPK13 mRNA abundance during the MELC pre-commitment period is expected to indicate an anticipation by these cells of a halt in cell division associated with the commitment event. We recently identified a protein target of association of the STPK13 protein kinase. It is a highly conserved RNA helicase which also shows cell cycle regulation. Both proteins are potentially good candidates as antimitotic targets.

Cell cycle- and terminal differentiation-associated regulation of the mouse mRNA encoding a conserved mitotic protein kinase
Lake RJ; Jelinek WR
1993 Dec;13(12):7793-7801, Molecular & cellular biology
We determined the nucleotide sequence of a mouse and a human cDNA, which we designate STPK13, that encodes an apparent protein kinase related to that encoded by the Drosophila melanogaster polo gene and the Saccharomyces cerevisiae CDC5 gene. The polo and CDC5 gene products are required for normal mitosis. The STPK13 mRNA is regulated during terminal erythrodifferentiation and during the cell cycle. Within the precommitment period of murine erythroleukemia cell terminal differentiation, most of the poly(A) tail is lost from the STPK13 mRNA, but the body of the mRNA remains unchanged in abundance; this poly(A) loss does not occur in mutant erythroleukemia cells that fail to commit to terminal differentiation. During the cell cycle, the abundance of the body of the STPK13 mRNA fluctuates. The mRNA is present in growing but not in nongrowing cells. It reaches a maximum abundance during G2/M phase, is absent or present at only low levels during G1 phase, and begins to reaccumulate at approximately the middle of S phase. The cell cycle-associated accumulation and loss of the STPK13 mRNA could cause a similar fluctuation in abundance of its encoded protein kinase, thereby providing a maximum amount during M phase, when the kinase is thought to function, and little or none at other times of the cell cycle. Posttranscriptional regulation must be responsible for the cell cycle-associated fluctuations because transcription rates are relatively constant during different times of the cell cycle when there are large differences in mRNA abundance

Replication of a plasmid bearing a human Alu-family repeat in monkey COS-7 cells
Johnson EM; Jelinek WR
1986 Jul;83(13):4660-4664, Proceedings of the National Academy of Sciences of the United States of America
Monkey COS-7 cells were transformed with BLUR8 DNA, a pBR322 plasmid containing a human Alu-family sequence at the BamHI site. Within 24 hr of transformation 2-5% of the BLUR8 molecules recovered resisted cleavage by Dpn I, indicating they had replicated. Electron microscopy revealed appropriately sized circular molecules with replication bubbles whose centers were mapped to the Alu insert. A 16-base-pair deletion within the Alu sequence prevented replication. The results indicate that certain Alu sequences can serve as origins of replication in COS-7 cells

4.5S RNA is encoded by hundreds of tandemly linked genes, has a short half-life, and is hydrogen bonded in vivo to poly(A)-terminated RNAs in the cytoplasm of cultured mouse cells
Schoeniger LO; Jelinek WR
1986 May;6(5):1508-1519, Molecular & cellular biology
4.5S RNA is a group of RNAs 90 to 94 nucleotides long (length polymorphism due to a varying number of UMP residues at the 3' end) that form hydrogen bonds with poly(A)-terminated RNAs isolated from mouse, hamster, or rat cells (W. R. Jelinek and L. Leinwand, Cell 15:205-214, 1978; F. Harada, N. Kato, and H.-O. Hoshino, Nucleic Acids Res. 7:909-917, 1979). We have cloned a gene that encodes the 4.5S RNA. It is repeated 850 (sigma = 54) times per haploid mouse genome and 690 (sigma = 59) times per haploid rat genome. Most, if not all, of the repeats in both species are arrayed in tandem. The repeat unit is 4,245 base pairs long in mouse DNA (the complete base sequence of one repeat unit is presented) and approximately 5,300 base pairs in rat DNA. This accounts for approximately 3 X 10(6) base pairs of genomic DNA in each species, or 0.1% of the genome. Cultured murine erythroleukemia cells contain 13,000 molecules per cell of the 4.5S RNA, which can be labeled to equilibrium in 90 min by [3H]uridine added to the culture medium. The 4.5S RNA, therefore, has a short half-life. The 4.5S RNA can be cross-linked in vivo by 4'-aminomethyl-4,5',8-trimethylpsoralen to murine erythroleukemia cell poly(A)-terminated cytoplasmic RNA contained in ribonucleoprotein particles

Repetitive sequence transcripts and U1 RNA in mouse oocytes and eggs
Kaplan G; Jelinek WR; Bachvarova R
1985 May;109(1):15-24, Developmental biology (Orlando)
Others have reported that about two-thirds of the polyadenylated RNA of sea urchin or frog eggs contains short interspersed repetitive sequence transcripts, a much larger proportion than that found in mRNA of somatic cells. Thus, it appears that incompletely processed transcripts accumulate in these oocytes. Also, in what may be a related phenomenon, the nuclear concentration of U1 RNA (involved in processing hnRNA) decreases during growth of frog oocytes. To pursue this question in mammals, Northern blots of RNA from mouse oocytes and eggs collected before and after meiotic maturation were probed with genomic clones containing rodent Alu-equivalent sequences. The Alu sequence is the predominant short interspersed repetitive element in the genome and is abundant in hnRNA. When compared on the basis of mRNA content, the oocyte and egg RNA contained less short repetitive sequence transcripts than liver or brain cytoplasmic RNA. Using a U1 RNA-specific probe, the concentration of U1 RNA in mouse oocyte nuclei was found to be quite similar to that in somatic cells, and U1 RNA was stable during meiotic maturation. These results suggest that processing of transcripts in mouse oocytes does not possess the unusual features observed in lower animals

Kpn I family of long-dispersed repeated DNA sequences of man: evidence for entry into genomic DNA of DNA copies of poly(A)-terminated Kpn I RNAs
DiGiovanni L; Haynes SR; Misra R; Jelinek WR
1983 Nov;80(21):6533-6537, Proceedings of the National Academy of Sciences of the United States of America
We have isolated eight cDNA clones complementary to the human Kpn I repeat and determined the base sequence of three. We have also determined a portion of the base sequences of three human Kpn I family members. The three cDNA sequences are extensively homologous with the 3' ends of the three genomic Kpn I family members and with a simian Kpn I family member recently described [Thayer, R. E. & Singer, M. F. (1983) Mol. Cell. Biol. 6, 967-973]. The genomic repeats terminate in regions of sequence rich in dAMP residues close to sequences at the 3' ends of the cDNA clones; a precise 3'-terminal nucleotide cannot be distinguished. These structural features are consistent with the dispersal of at least some Kpn I family members by entry into genomic DNA of copies of Kpn I RNA transcripts. Each cDNA contains a long poly(dAMP) homopolymer at its 3' end and either one or two A-A-T-A-A-A polyadenylylation signal sequences upstream from it, suggesting that Kpn I family members may be transcribed by RNA polymerase II

Discrete and heterogeneous high molecular weight RNAs complementary to a long dispersed repeat family (a possible transposon) of human DNA
Kole LB; Haynes SR; Jelinek WR
1983 Apr 5;165(2):257-286, Journal of molecular biology
Approximately 1% of heterogeneous nuclear RNA and approximately 0.035% of cytoplasmic RNA from a cultured line of human lymphoblastoid cells is complementary to a long dispersed repetitious sequence that comprises at least 6% of human DNA. The complementary nuclear RNA is both heterogeneously and discretely sized and is present in both poly(A)-terminated and non-poly(A)-terminated molecules. The complementary cytoplasmic RNA is mainly in discretely sized molecules ranging in size from approximately 600 to 8200 bases, some of which are most abundantly represented in poly(A)-terminated molecules, whereas others are most abundantly represented in non-poly(A)-terminated molecules. Few, if any, of the complementary cytoplasmic RNAs can be found associated with polyribosomes. The dispersed repeat sequence exhibits substantial restriction enzyme fragment length polymorphisms in human DNA and is also present in mouse DNA, although some regions of the human repeat appear to be more abundantly represented in mouse DNA than are other regions

The Alu family of dispersed repetitive sequences
Schmid CW; Jelinek WR
1982 Jun 4;216(4550):1065-1070, Science
A family of related sequences that includes approximately 500,000 members is the most prominent short dispersed repeat family in primate and rodent DNA's. The primate sequence is approximately 300 base pairs in length and is composed of two imperfectly repeated monomer units, whereas the rodent repeat consists of only a single monomer. Properties of this repeat sequence, its flanking sequences in chromosomal DNA, and RNA's transcribed from it suggest that it may be a mobile DNA element inserted at hundreds of thousands of different chromosomal locations

Low molecular weight RNAs transcribed in vitro by RNA polymerase III from Alu-type dispersed repeats in Chinese hamster DNA are also found in vivo
Haynes SR; Jelinek WR
1981 Oct;78(10):6130-6134, Proceedings of the National Academy of Sciences of the United States of America
An Alu-type dispersed repeat previously identified in a cloned fragment of Chinese hamster DNA [Haynes, S. R., Toomey, T. P., Leinwand, L. & Jelinek, W. R. (1981) Mol. Cell. Biol. 1, 573-583] serves as a template for cell-free transcription of discrete low molecular weight RNAs by RNA polymerase III [RNA nucleotidyltransferase (DNA-directed), EC 2.7.7.6]. A class of analogous RNAs has been isolated from growing Chinese hamster cells by hybridization of total low molecular weight nuclear RNAs to the cloned DNA fragment from which cell-free transcription occurs. Two-dimensional analysis of RNase digestion products of these RNAs suggests that they are transcribed from multiple members of the Alu-type dispersed repeat family

The Chinese hamster Alu-equivalent sequence: a conserved highly repetitious, interspersed deoxyribonucleic acid sequence in mammals has a structure suggestive of a transposable element
Haynes SR; Toomey TP; Leinwand L; Jelinek WR
1981 Jul;1(7):573-583, Molecular & cellular biology
A consensus sequence has been determined for a major interspersed deoxyribonucleic acid repeat in the genome of Chinese hamster ovary cells (CHO cells). This sequence is extensively homologous to (i) the human Alu sequence (P. L. Deininger et al., J. Mol. Biol., in press), (ii) the mouse B1 interspersed repetitious sequence (Krayev et al., Nucleic Acids Res. 8:1201-1215, 1980) (iii) an interspersed repetitious sequence from African green monkey deoxyribonucleic acid (Dhruva et al., Proc. Natl. Acad. Sci. U.S.A. 77:4514-4518, 1980) and (iv) the CHO and mouse 4.5S ribonucleic acid (this report; F. Harada and N. Kato, Nucleic Acids Res. 8:1273-1285, 1980). Because the CHO consensus sequence shows significant homology to the human Alu sequence it is termed the CHO Alu-equivalent sequence. A conserved structure surrounding CHO Alu-equivalent family members can be recognized. It is similar to that surrounding the human Alu and the mouse B1 sequences, and is represented as follows: direct repeat-CHO-Alu-A-rich sequence-direct repeat. A composite interspersed repetitious sequence has been identified. Its structure is represented as follows: direct repeat-residue 47 to 107 of CHO-Alu-non-Alu repetitious sequence-A-rich sequence-direct repeat. Because the Alu flanking sequences resemble those that flank known transposable elements, we think it likely that the Alu sequence dispersed throughout the mammalian genome by transposition

Ubiquitous, interspersed repeated sequences in mammalian genomes
Jelinek WR; Toomey TP; Leinwand L; Duncan CH; Biro PA; Choudary PV; Weissman SM; Rubin CM; Houck CM; Deininger PL; Schmid CW
1980 Mar;77(3):1398-1402, Proceedings of the National Academy of Sciences of the United States of America
DNA base sequence comparisons demonstrate that the principal family of 300-nucleotide interspersed human DNA sequences, the repetitive double-strand regions of HeLa cell heterogeneous nuclear RNA, and specific RNA polymerase III in vitro transcripts of cloned human DNA sequences are all representatives of a closely related family of sequences. A segment of approximately 30 residues of these sequences is highly conserved in mammalian evolution because it is also present in the interspersed repeated DNA sequences of Chinese hamsters. Further DNA sequence comparisons demonstrate that a portion of this highly conserved segment of repetitive mamalian DNA sequence is similar to a sequence found within a low molecular weight RNA that hydrogen-bonds to poly(A)-terminated RNA molecules of Chinese hamsters and a sequence that forms half of a perfect inverted repeat near the origin of DNA replication in papovaviruses

Inverted repeated DNA from Chinese hamster ovary cells studied with cloned DNA fragments
Jelinek WR
1978 Jun;75(6):2679-2683, Proceedings of the National Academy of Sciences of the United States of America
Fragments from the DNA of Chinese hamster ovary cells produced by restriction endonuclease EcoRI were cloned in Charon 16A lambda bacteriophage and examined for the ability to hybridize in situ with 32P-labeled double-stranded regions from heterogeneous nuclear RNA (hnRNA). Of 235 clones tested, 87 (37%) contained sequences that hybridized with the double-stranded hnRNA. Nine of these were examined for the presence of inverted repeat DNA structures (ir-DNA) by electron microscopy. All nine contained at least two elements of ir-DNA. Analysis of heteroduplexes formed from the DNAs of the different clones as well as T1 fingerprint analysis of the double-stranded hnRNA hybridized to each of the nine clones suggest that there is detectable nucleotide sequence homology in the various ir-DNAs. There are ca 3 X 10(5) ir-DNA pairs in the haploid Chinese hamster ovary cell genome

Mapping of inverted repeated DNA sequences within the genome of simian virus 40
Hsu MT; Jelinek WR
1977 Apr;74(4):1631-1634, Proceedings of the National Academy of Sciences of the United States of America
Single-stranded, linear DNA of simian virus 40 (SV40) created by denaturing the endonuclease EcoRI- or Hpa II-generated, linear, double-stranded products from form I DNA of SV40 was analyzed for regions of inverted repeated sequences by visualization with the electron microscope. Six hairpin loops were found at positions 0.11-0.30 (two loops forming a 'rabbit ears' structure), 0.47-0.52, 0.63-0.68, 0.70-0.76, and 0.90-0.96. The nucleotide sequences within all of these inverted repeats may be related since the looped regions can crosshybridize with one another and, thus, the SV40 genome may contain regions of interspersed repeated and unique sequences. The map positions of the 3' and 5' ends of the early and late messenger RNAs, as determined by others, lie within regions of inverted repeated sequences. Previously recorded recombination events that occurred either within the SV40 genome or between SV40 DNA and other genomes have apparently occurred frequently at positions of inverted repeated sequences within the SV40 DNA
