Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF00112 Peptidase_C1 Papain family cysteine protease Domain PFAM PF00112
A PF08246 Inhibitor_I29 Cathepsin propeptide inhibitor domain (I29) Domain This domain is found at the N-terminus of some C1 peptidases such as Cathepsin L where it acts as a propeptide. There are also a number of proteins that are composed solely of multiple copies of this domain such as the peptidase inhibitor salarin Swiss:Q70SU8. This family is classified as I29 by MEROPS.
