ubiquitin carboxyl-terminal hydrolase 27; deubiquitinating enzyme 27; ubiquitin carboxyl-terminal hydrolase 22-like; ubiquitin thiolesterase 27; ubiquitin-specific-processing protease 27; X-linked ubiquitin carboxyl-terminal hydrolase 27 (USP27X, USP22L, USP27)

Function
- thiol-dependent hydrolysis of ester, thioester, amide, peptide & isopeptide bonds formed by the C-terminal Gly of ubiquitin
Structure
- belongs to the peptidase C19 family
- although strongly related to USP22, which deubiquitinates histones, lacks the N-terminal UBP-type Zn+2 finger, suggesting it does not have the ability to deubiquitinate histones
