Description:
Complementary DNA's that encode an adenylyl cyclase were isolated from a bovine brain library. Most of the deduced amino acid sequence of 1134 residues is divisible into two alternating sets of hydrophobic and hydrophilic domains. Each of the two large hydrophobic domains appears to contain six transmembrane spans. Each of the two large hydrophilic domains contains a sequence that is homologous to a single cytoplasmic domain of several guanylyl cyclases; these sequences may represent nucleotide binding sites. An unexpected topographical resemblance between adenylyl cyclase and various plasma membrane channels and transporters was observed. This structural complexity suggests possible, unappreciated functions for this important enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krupinski, J -- Coussen, F -- Bakalyar, H A -- Tang, W J -- Feinstein, P G -- Orth, K -- Slaughter, C -- Reed, R R -- Gilman, A G -- CA16519/CA/NCI NIH HHS/ -- GM12230/GM/NIGMS NIH HHS/ -- GM34497/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jun 30;244(4912):1558-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2472670" target="_blank"〉PubMed〈/a〉
