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. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- SIMILARITY: Belongs to the pancreatic ribonuclease family.
CC {ECO:0000305}.
