General annotation (Comments)

Function

Deubiquitinase that plays a key role in the spindle checkpoint by preventing premature anaphase onset. Acts by specifically mediating deubiquitination of cdc20, a negative regulator of the anaphase promoting complex/cyclosome (APC/C) By similarity.

Catalytic activity

Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).

Subcellular location

Nucleus By similarity.

Sequence similarities

Belongs to the peptidase C19 family. USP44 subfamily.

Contains 1 UBP-type zinc finger.

Contains 1 USP domain.
