Protein attributes

Sequence length	177 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Clavin has the same substrate-specificity than alpha-sarcin. It is specific for purines in both single- and double-stranded RNA. Its toxic action on eukaryotic cells is the result of cleavage of a single phosphodiester bond in the 60S subunit of ribosomes. Ref.1
Subcellular location	Secreted By similarity.
Sequence similarities	Belongs to the ribonuclease U2 family.
