CathepsinC_exc

CathepsinC_exc
PFAM accession number:PF08773
Interpro abstract (IPR014882):

Cathepsin C (dipeptidyl peptidase I) is the physiological activator of a group of serine proteases. This protein corresponds to the exclusion domain whose structure excludes the approach of a polypeptide apart from its termini. It forms an enclosed beta barrel structure composed from 8 anti-parallel beta strands [(PUBMED:11726493)]. Based on a structural comparison and interaction data, it is suggested that the exclusion domain originates from a metallo-protease inhibitor [(PUBMED:11726493)].

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