Protein attributes

Sequence length	152 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Endonuclease that catalyzes the cleavage of RNA on the 3' side of pyrimidine nucleotides. Acts on single stranded and double stranded RNA By similarity.
Catalytic activity	Endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides ending in Cp or Up with 2',3'-cyclic phosphate intermediates.
Subunit structure	Monomer. Interacts with and forms tight 1:1 complexes with RNH1. Dimerization of two such complexes may occur. Interaction with RNH1 inhibits this protein By similarity.
Subcellular location	Secreted.
Sequence similarities	Belongs to the pancreatic ribonuclease family.
