    Description: Activation of the serine-threonine kinase p34cdc2 at an inappropriate time during the cell cycle leads to cell death that resembles apoptosis. Premature activation of p34cdc2 was shown to be required for apoptosis induced by a lymphocyte granule protease. The kinase was rapidly activated and tyrosine dephosphorylated at the initiation of apoptosis. DNA fragmentation and nuclear collapse could be prevented by blocking p34cdc2 activity with excess peptide substrate, or by inactivating p34cdc2 in a temperature-sensitive mutant. Premature p34cdc2 activation may be a general mechanism by which cells induced to undergo apoptosis initiate the disruption of the nucleus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shi, L -- Nishioka, W K -- Th'ng, J -- Bradbury, E M -- Litchfield, D W -- Greenberg, A H -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1143-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Manitoba Institute of Cell Biology, University of Manitoba, Winnipeg, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108732" target="_blank"〉PubMed〈/a〉

    Description: The regulation of DNA replication during the eukaryotic cell cycle was studied in a system where cell free replication of simian virus 40 (SV40) DNA was used as a model for chromosome replication. A factor, RF-S, was partially purified from human S phase cells based on its ability to activate DNA replication in extracts from G1 cells. RF-S contained a human homologue of the Schizosaccharomyces pombe p34cdc2 kinase, and this kinase was necessary for RF-S activity. The limiting step in activation of the p34 kinase at the G1 to S transition may be its association with a cyclin since addition of cyclin A to a G1 extract was sufficient to start DNA replication. These observations suggest that the role of p34cdc2 in controlling the start of DNA synthesis has been conserved in evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉D'Urso, G -- Marraccino, R L -- Marshak, D R -- Roberts, J M -- New York, N.Y. -- Science. 1990 Nov 9;250(4982):786-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Basic Sciences, Fred Hutchinson Cancer Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2173140" target="_blank"〉PubMed〈/a〉

    Description: Heterokaryon studies suggest that senescent and quiescent human diploid fibroblasts (HDF) contain a common inhibitor of entry into S phase. DNA synthesis can be induced in senescent and quiescent HDF by fusing them with cells containing DNA viral oncogenes such as SV40 T antigen, adenovirus E1A, or human papillomavirus E7. Both senescent and quiescent HDF contained the unphosphorylated form (p110Rb) of the retinoblastoma protein, a putative inhibitor of proliferation. After serum stimulation, senescent HDF did not phosphorylate p110Rb and did not enter S phase, whereas quiescent HDF phosphorylated p110Rb and entered S phase. These findings, combined with the observations that T antigen, E1A, and E7 form complexes with, and presumably inactivate, unphosphorylated p110Rb, suggest that failure to phosphorylate p110Rb may be an immediate cause of failure to enter S phase in senescent HDF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stein, G H -- Beeson, M -- Gordon, L -- AG 00947/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):666-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular, and Developmental Biology, University of Colorado, Boulder 80309-0347.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2166342" target="_blank"〉PubMed〈/a〉

    Description: The major autophosphorylation sites of the rat beta II isozyme of protein kinase C were identified. The modified threonine and serine residues were found in the amino-terminal peptide, the carboxyl-terminal tail, and the hinge region between the regulatory lipid-binding domain and the catalytic kinase domain. Because this autophosphorylation follows an intrapeptide mechanism, extraordinary flexibility of the protein is necessary to phosphorylate the three regions. Comparison of the sequences surrounding the modified residues showed no obvious recognition motif nor any similarity to substrate phosphorylation sites, suggesting that proximity to the active site may be the primary criterion for their phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flint, A J -- Paladini, R D -- Koshland, D E Jr -- DK09765/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1990 Jul 27;249(4967):408-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2377895" target="_blank"〉PubMed〈/a〉

    Description: Homologous or agonist-specific desensitization of beta-adrenergic receptors is thought to be mediated by a specific kinase, the beta-adrenergic receptor kinase (beta ARK). However, recent data suggest that a cofactor is required for this kinase to inhibit receptor function. The complementary DNA for such a cofactor was cloned and found to encode a 418-amino acid protein homologous to the retinal protein arrestin. The protein, termed beta-arrestin, was expressed and partially purified. It inhibited the signaling function of beta ARK-phosphorylated beta-adrenergic receptors by more than 75 percent, but not that of rhodopsin. It is proposed that beta-arrestin in concert with beta ARK effects homologous desensitization of beta-adrenergic receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lohse, M J -- Benovic, J L -- Codina, J -- Caron, M G -- Lefkowitz, R J -- DK19318/DK/NIDDK NIH HHS/ -- HL16037/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1990 Jun 22;248(4962):1547-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, Biochemistry and Cell Biology, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2163110" target="_blank"〉PubMed〈/a〉

    Description: The erbB2 oncogene encodes a 185-kilodalton transmembrane protein whose sequence is similar to the epidermal growth factor receptor (EGFR). A 30-kilodalton factor (gp30) secreted from MDA-MB-231 human breast cancer cells was shown to be a ligand for p185erbB2. An antibody to EGFR abolished the tyrosine phosphorylation induced by EGF and transforming growth factor-alpha (TGF-alpha) but only partially blocked that produced by gp30 in SK-BR-3 breast cancer cells. In two cell lines that overexpress erbB2 but do not expresss EGFR (MDA-MB-453 breast cancer cells and a Chinese hamster ovary cell line that had been transfected with erbB2), phosphorylation of p185erbB2 was induced only by gp30. The gp30 specifically inhibited the growth of cells that overexpressed p185erbB2. An antibody to EGFR had no effect on the inhibition of SK-BR-3 cell colony formation obtained with gp30. Thus, it appeared that gp30 interacted directly with the EGFR and erbB2. Direct binding of gp30 to p185erbB2 was confirmed by binding competition experiments, where gp30 was found to displace the p185erbB2 binding of a specific antibody to p185erbB2. The evidence described here suggests that gp30 is a ligand for p185erbB2.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lupu, R -- Colomer, R -- Zugmaier, G -- Sarup, J -- Shepard, M -- Slamon, D -- Lippman, M E -- New York, N.Y. -- Science. 1990 Sep 28;249(4976):1552-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vincent T.

    Description: The isocitrate dehydrogenase of Escherichia coli is an example of a ubiquitous class of enzymes that are regulated by covalent modification. In the three-dimensional structure of the enzyme-substrate complex, isocitrate forms a hydrogen bond with Ser113, the site of regulatory phosphorylation. The structures of Asp113 and Glu113 mutants, which mimic the inactivation of the enzyme by phosphorylation, show minimal conformational changes from wild type, as in the phosphorylated enzyme. Calculations based on observed structures suggest that the change in electrostatic potential when a negative charge is introduced either by phosporylation or site-directed mutagenesis is sufficient to inactivate the enzyme. Thus, direct interaction at a ligand binding site is an alternative mechanism to induced conformational changes from an allosteric site in the regulation of protein activity by phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurley, J H -- Dean, A M -- Sohl, J L -- Koshland, D E Jr -- Stroud, R M -- GM 24485/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 31;249(4972):1012-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco 94143-0448.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2204109" target="_blank"〉PubMed〈/a〉

    Description: Rap1A is a low molecular weight guanosine triphosphate (GTP)-binding protein in human neutrophil membranes whose cellular function is unknown. Rap1A was found to form stoichiometric complexes with the cytochrome b558 component of the phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase system. The (guanosine-5'-O-(3-thiotriphosphate) (GTP-gamma-S)-bound form of Rap1A bound more tightly to cytochrome b558 than did the guanosine diphosphate-bound form. No complex formation was observed between cytochrome b558 and H-Ras-GTP-gamma-S or Rap1A-GTP-gamma-S that had been heat-inactivated, nor between Rap1A-GTP-gamma-S and hydrophobic proteins serving as controls. Complex formation between Rap1A-GTP-gamma-S and cytochrome b558 was inhibited by phosphorylation of Rap1A with cyclic adenosine monophosphate (cAMP)-dependent protein kinase. These observations suggest that Rap1A may participate in the structure or regulation of the NADPH oxidase system and that this function of the Rap1A protein may be altered by phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bokoch, G M -- Quilliam, L A -- Bohl, B P -- Jesaitis, A J -- Quinn, M T -- 5RO126711/PHS HHS/ -- GM39434/GM/NIGMS NIH HHS/ -- GM44428/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1794-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1763330" target="_blank"〉PubMed〈/a〉

    Description: Voltage-gated sodium channels are responsible for generation of action potentials in excitable cells. Activation of protein kinase C slows inactivation of sodium channels and reduces peak sodium currents. Phosphorylation of a single residue, serine 1506, that is located in the conserved intracellular loop between domains III and IV and is involved in inactivation of the sodium channel, is required for both modulatory effects. Mutant sodium channels lacking this phosphorylation site have normal functional properties in unstimulated cells but do not respond to activation of protein kinase C. Phosphorylation of this conserved site in sodium channel alpha subunits may regulate electrical activity in a wide range of excitable cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, J W -- Numann, R -- Murphy, B J -- Scheuer, T -- Catterall, W A -- GM07270/GM/NIGMS NIH HHS/ -- NS15751/NS/NINDS NIH HHS/ -- NS25704/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 8;254(5033):866-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1658937" target="_blank"〉PubMed〈/a〉

    Description: RAP30/74 is a heteromeric general transcription initiation factor that binds to mammalian RNA polymerase II. The RAP30 subunit contains a region that is similar in amino acid sequence to the RNA polymerase-binding domain of the Escherichia coli transcription initiation factor sigma 70 (sigma 70). Mammalian RNA polymerase II specifically protected a serine residue in the sigma 70-related region of RAP30 from phosphorylation in vitro. In addition, human RAP30/74 bound to Escherichia coli RNA polymerase and was displaced by sigma 70. These results suggest that RAP30 and sigma 70 have functionally related RNA polymerase-binding regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCracken, S -- Greenblatt, J -- New York, N.Y. -- Science. 1991 Aug 23;253(5022):900-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1652156" target="_blank"〉PubMed〈/a〉
