Description:
In the genetic code, UGA serves as a stop signal and a selenocysteine codon, but no computational methods for identifying its coding function are available. Consequently, most selenoprotein genes are misannotated. We identified selenoprotein genes in sequenced mammalian genomes by methods that rely on identification of selenocysteine insertion RNA structures, the coding potential of UGA codons, and the presence of cysteine-containing homologs. The human selenoproteome consists of 25 selenoproteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kryukov, Gregory V -- Castellano, Sergi -- Novoselov, Sergey V -- Lobanov, Alexey V -- Zehtab, Omid -- Guigo, Roderic -- Gladyshev, Vadim N -- GM61603/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 30;300(5624):1439-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Nebraska, Lincoln, NE 68588-0664, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12775843" target="_blank"〉PubMed〈/a〉
