    The Neurospora checkpoint kinase 2: a regulatory link between the circadian and cell cycles (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-01
    Description: The clock gene period-4 (prd-4) in Neurospora was identified by a single allele displaying shortened circadian period and altered temperature compensation. Positional cloning followed by functional tests show that PRD-4 is an ortholog of mammalian checkpoint kinase 2 (Chk2). Expression of prd-4 is regulated by the circadian clock and, reciprocally, PRD-4 physically interacts with the clock component FRQ, promoting its phosphorylation. DNA-damaging agents can reset the clock in a manner that depends on time of day, and this resetting is dependent on PRD-4. Thus, prd-4, the Neurospora Chk2, identifies a molecular link that feeds back conditionally from circadian output to input and the cell cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pregueiro, Antonio M -- Liu, Qiuyun -- Baker, Christopher L -- Dunlap, Jay C -- Loros, Jennifer J -- MH44651/MH/NIMH NIH HHS/ -- P01 GM068087/GM/NIGMS NIH HHS/ -- R01 GM034985/GM/NIGMS NIH HHS/ -- R37GM34985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):644-9.

    Genomic heterogeneity of AIDS retroviral isolates from North America and Zaire (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-22
    Description: In an analysis of the genomic variation of AIDS retroviral isolates from patients living in New York, Alabama, and Zaire, restriction maps were constructed by using seven enzymes, each known to cleave the proviral DNA more than once, in conjunction with Southern blot analysis. The maps of LAV, HTLV-III, and ARV-2 as deduced from their published nucleotide sequences were included in this analysis. The results demonstrated that (i) several "signature" restriction sites were common to all isolates; (ii) with the exception of LAV and HTLV-III, the North American and European isolates were all different from one another and showed no geographical specificity; (iii) the African isolates as a group were more diverse than those from North America and Europe; and (iv) the genomic variability was concentrated within the env gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benn, S -- Rutledge, R -- Folks, T -- Gold, J -- Baker, L -- McCormick, J -- Feorino, P -- Piot, P -- Quinn, T -- Martin, M -- New York, N.Y. -- Science. 1985 Nov 22;230(4728):949-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2997922" target="_blank"〉PubMed〈/a〉

    Sequence and expression of human estrogen receptor complementary DNA (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-03-07
    Description: The mechanism by which the estrogen receptor and other steroid hormone receptors regulate gene expression in eukaryotic cells is not well understood. In this study, a complementary DNA clone containing the entire translated portion of the messenger RNA for the estrogen receptor from MCF-7 human breast cancer cells was sequenced and then expressed in Chinese hamster ovary (CHO-K1) cells to give a functional protein. An open reading frame of 1785 nucleotides in the complementary DNA corresponded to a polypeptide of 595 amino acids and a molecular weight of 66,200, which is in good agreement with published molecular weight values of 65,000 to 70,000 for the estrogen receptor. Homogenates of transformed Chinese hamster ovary cells containing a protein that bound [3H]estradiol and sedimented as a 4S complex in salt-containing sucrose gradients and as an 8 to 9S complex in the absence of salt. Interaction of this receptor-[3H]estradiol complex with a monoclonal antibody that is specific for primate ER confirms the identity of the expressed complementary DNA as human estrogen receptor. Amino acid sequence comparisons revealed significant regional homology among the human estrogen receptor, the human glucocorticoid receptor, and the putative v-erbA oncogene product. This suggests that steroid receptor genes and the avian erythroblastosis viral oncogene are derived from a common primordial gene. The homologous region, which is rich in cysteine, lysine, and arginine, may represent the DNA-binding domain of these proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greene, G L -- Gilna, P -- Waterfield, M -- Baker, A -- Hort, Y -- Shine, J -- CA-02897/CA/NCI NIH HHS/ -- HD17103/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1150-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3753802" target="_blank"〉PubMed〈/a〉
