Cytoplasmic expression in exocrine pancreas and gastrointestinal mucosa.
DATA RELIABILITY
Data reliability description
Secreted protein, tissue location of RNA and protein might differ and correlation is complex. External characterization data supports antibody staining.
Ribonuclease, RNase A family, 1 (pancreatic) (HGNC Symbol)
Entrez gene summary
This 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. It 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]
