NCIt definition : Human SELENOP wild-type allele is located in the vicinity of 5q12 and is approximately
88 kb in length. This allele, which encodes selenoprotein P, plays a role in selenium
distribution.;
NCIt note : Selenium is found not as a cofactor in mammalian proteins but as a selenocysteine
residue, which is encoded by UGA. In order for the UGA codon to be translated as a
selenocysteine rather than a stop codon, a stem-loop structure called a selenocysteine
insertion sequence (SECIS) must be present in the 3' untranslated region (UTR) of
the selenoprotein mRNA. (OMIM);
