DUF4650

 DUF4650
PFAM accession number:PF15509
Interpro abstract (IPR029388):

This domain lies to the C terminus of the ubiquitin-specific peptidase-like proteins from veterbrates ( IPR028890 ). Many peptidases require exosites (a secondary binding site that is remote from the active site) to recognise physiological substrates. This domain might be acting as the exosite for the peptidase.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry DUF4650
