Protein attributes

Sequence length	30 AA.
Sequence status	Fragment.
Protein existence	Evidence at protein level

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.
Tissue specificity	Pancreas.
Sequence similarities	Belongs to the pancreatic ribonuclease family.
