    Expression of a cloned rat brain potassium channel in Xenopus oocytes (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-14
    Description: Potassium channels are ubiquitous membrane proteins with essential roles in nervous tissue, but little is known about the relation between their function and their molecular structure. A complementary DNA library was made from rat hippocampus, and a complementary DNA clone (RBK-1) was isolated. The predicted sequence of the 495-amino acid protein is homologous to potassium channel proteins encoded by the Shaker locus of Drosophila and differs by only three amino acids from the expected product of a mouse clone MBK-1. Messenger RNA transcribed from RBK-1 in vitro directed the expression of potassium channels when it was injected into Xenopus oocytes. The potassium current through the expressed channels resembles both the transient (or A) and the delayed rectifier currents reported in mammalian neurons and is sensitive to both 4-aminopyridine and tetraethylammonium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christie, M J -- Adelman, J P -- Douglass, J -- North, R A -- DA03160/DA/NIDA NIH HHS/ -- DA03161/DA/NIDA NIH HHS/ -- DA04154/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):221-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539643" target="_blank"〉PubMed〈/a〉

    Two mammalian genes transcribed from opposite strands of the same DNA locus (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-03-20
    Description: This report describes the characterization of a genomic locus in the rat that encodes overlapping genes occupying both strands of the same piece of DNA. One gene (strand) encodes gonadotropin-releasing hormone (GnRH). A second gene, SH, is transcribed from the other DNA strand to produce RNA of undefined function. The RNAs transcribed from each DNA strand are spliced and polyadenylated, and share significant exon domains. GnRH is expressed in the central nervous system while SH transcripts are present in the heart. Thus, the genome of a mammalian organism encodes two distinct genes by using both strands of the same DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adelman, J P -- Bond, C T -- Douglass, J -- Herbert, E -- AM-16879/AM/NIADDK NIH HHS/ -- AM-30155/AM/NIADDK NIH HHS/ -- DA-02736/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1987 Mar 20;235(4795):1514-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3547652" target="_blank"〉PubMed〈/a〉
