NCIt definition : Human SELENON wild-type allele is located in the vicinity of 1p36.11 and is approximately
18 kb in length. This allele, which encodes selenoprotein N, is involved in calcium
homeostasis, ryanodine receptor (RyR) activity and the cellular response to oxidative
stress. Mutations in the gene are associated with rigid spine muscular dystrophy 1.;
NCIt note : The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated
the selenocysteine (Sec) insertion sequence (SECIS) element, which is necessary for
the recognition of UGA codons as Sec codons rather than stop signals. Additionally,
the SELENON gene contains a second stop-codon redefinition element (SRE) adjacent
to the UGA codon. (EntrezGene);
