Protein attributes

Sequence length	124 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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 By similarity.
Subcellular location	Secreted.
Tissue specificity	Pancreas.
Post-translational modification	Swamp breed ribonuclease do not bind carbohydrate, but there is evidence of a polymorphic form that does.
Miscellaneous	The sequence of the river breed (Italy) is shown, the other type is known as swamp-type (Indonesia).
Sequence similarities	Belongs to the pancreatic ribonuclease family.
