This RNASE1 gene encodes a member of the pancreatic-type of secretory ribonucleases, a subset of the ribonuclease A superfamily. The encoded endonuclease cleaves internal phosphodiester RNA bonds on the 3'-side of pyrimidine bases. RNASE1 prefers poly(C) as a substrate and hydrolyzes 2',3'-cyclic nucleotides, with a pH optimum near 8.0. The encoded protein is monomeric and more commonly acts to degrade ds-RNA over ss-RNA. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
OMIM-Description for RNase A / Ribonuclease A / RNASE1N
Pancreatic ribonuclease (RNase A)(EC 188.8.131.52) is one of the digestive enzymes secreted in abundance by the pancreas.
RNase A / Ribonuclease A / RNASE1
Ribonuclease A (RNase A) is a pancreatic ribonuclease that cleaves single-stranded RNA. Bovine pancreatic RNase A is one of the classic model systems of protein science.
