CC   -!- FUNCTION: Endonuclease that catalyzes the cleavage of RNA on the 3'
CC       side of pyrimidine nucleotides. Acts on single-stranded and double-
CC       stranded RNA (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an [RNA] containing cytidine + H2O = an [RNA]-3'-cytidine-3'-
CC         phosphate + a 5'-hydroxy-ribonucleotide-3'-[RNA].; EC=4.6.1.18;
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an [RNA] containing uridine + H2O = an [RNA]-3'-uridine-3'-
CC         phosphate + a 5'-hydroxy-ribonucleotide-3'-[RNA].; EC=4.6.1.18;
CC   -!- SUBUNIT: Monomer. Interacts with and forms tight 1:1 complexes with
CC       RNH1. Dimerization of two such complexes may occur. Interaction with
CC       RNH1 inhibits this protein (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Pancreas.
CC   -!- SIMILARITY: Belongs to the pancreatic ribonuclease family.
CC       {ECO:0000305}.
