A, B [auth C] | PF08246 | Cathepsin propeptide inhibitor domain (I29) (Inhibitor_I29) | Cathepsin propeptide inhibitor domain (I29) | 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 Sw ... | Domain |
