    Purification, cloning, and expression of ciliary neurotrophic factor (CNTF) (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-24
    Description: Ciliary neurotrophic factor (CNTF) is one of a small number of proteins with neurotrophic activities distinct from nerve growth factor (NGF). CNTF has now been purified and cloned and the primary structure of CNTF from rabbit sciatic nerve has been determined. Biologically active CNTF has been transiently expressed from a rabbit complementary DNA clone. CNTF is a neural effector without significant sequence homologies to any previously reported protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Mismer, D -- Lile, J D -- Armes, L G -- Butler, E T 3rd -- Vannice, J L -- Collins, F -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1023-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Protein Chemistry Group, Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2587985" target="_blank"〉PubMed〈/a〉

    A family of putative potassium channel genes in Drosophila (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-17
    Description: Mutant flies in which the gene coding for the Shaker potassium channel is deleted still have potassium currents similar to those coded by the Shaker gene. This suggests the presence of a family of Shaker-like genes in Drosophila. By using a Shaker complementary DNA probe and low-stringency hybridization, three additional family members have now been isolated, Shab, Shaw, and Shal. The Shaker family genes are not clustered in the genome. The deduced proteins of Shab, Shaw, and Shal have high homology to the Shaker protein; the sequence identity of the integral membrane portions is greater than 50 percent. These genes are organized similarly to Shaker in that only a single homology domain containing six presumed membrane-spanning segments common to all voltage-gated ion channels is coded by each messenger RNA. Thus, potassium channel diversity could result from an extended gene family, as well as from alternate splicing of the Shaker primary transcript.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butler, A -- Wei, A G -- Baker, K -- Salkoff, L -- 1 RO1 NS24785-01/NS/NINDS NIH HHS/ -- GMO 7200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):943-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2493160" target="_blank"〉PubMed〈/a〉

    RNA processing generates the mature 3' end of yeast CYC1 messenger RNA in vitro (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-02
    Description: In whole cell extracts of Saccharomyces cerevisiae, incubation of precursor mRNA transcripts encoding the sequences essential in vivo for forming the 3' end of the iso-1-cytochrome c mRNA (CYC1) revealed an endonuclease activity with the characteristics required for producing the mature mRNA 3' end. The observed cleavage in vitro is (i) accurate, occurring at or near the polyadenylation site of CYC1 RNA, (ii) 30 to 50 percent efficient, (iii) adenosine triphosphate dependent, (iv) specific for the 3' ends of at least two yeast pre-mRNA's, and (v) absent with related pre-mRNA's carrying mutations that abolish correct 3' end formation in vivo. In addition, a second activity in the extract polyadenylates the product under appropriate conditions. Thus, the mature 3' ends of yeast mRNA's may be generated by endonucleolytic cleavage and polyadenylation rather than by transcription termination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butler, J S -- Platt, T -- 5-RO1-GM35658/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Dec 2;242(4883):1270-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Rochester Medical Center, NY 14642.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2848317" target="_blank"〉PubMed〈/a〉

    Genomic organization and deduced amino acid sequence of a putative sodium channel gene in Drosophila (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-08-14
    Description: The deduced amino acid sequence of a Drosophila gene isolated with a vertebrate sodium channel complementary DNA probe revealed an organization virtually identical to the vertebrate sodium channel protein; four homologous domains containing all putative membrane-spanning regions are repeated in tandem with connecting linkers of various sizes. All areas of the protein presumed to be critical for channel function show high evolutionary conservation. These include those proposed to function in voltage-sensitive gating, inactivation, and ion selectivity. All 24 putative gating charges of the vertebrate protein are in identical positions in the Drosophila gene. Ten introns interrupt the coding regions of the four homology units; introns with positions conserved among homology units bracket a region hypothesized to be the selectivity filter for the channel. The Drosophila gene maps to the right arm of the second chromosome in region 60D-E. This position does not coincide with any known mutations that confer behavioral phenotypes, but is close to the seizure locus (60A-B), which has been hypothesized to code for a voltage-sensitive sodium channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salkoff, L -- Butler, A -- Wei, A -- Scavarda, N -- Giffen, K -- Ifune, C -- Goodman, R -- Mandel, G -- 1 R01 NS24785-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 14;237(4816):744-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2441469" target="_blank"〉PubMed〈/a〉
