NCIt definition : Human GPX3 wild-type allele is located 5q33.1 and is approximately 9 kb in length.
This allele, which encodes glutathione peroxidase 3 protein, plays a role in hydrogen
peroxide and lipid peroxide metabolism.;
NCIt note : The protein encoded by the GPX3 gene contains 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.;
