Protein Classification

C1 family peptidase; cystatin family protein( domain architecture ID 10289479)

C1 family peptidase (also called papain family protein) is a papain-like cysteine peptidase that catalyzes the hydrolysis of peptide bonds in substrates using a catalytic dyad of Cys and His residues| cystatin family protein similar to cystatins which are a family of cysteine protease inhibitors

67-129 8.12e-38

Secreted phosphoprotein 24 (Spp-24) cystatin-like domain; This family represents a conserved region approximately 60 residues long within secreted phosphoprotein 24 (Spp-24), which seems to be restricted to vertebrates. This is a non-collagenous protein found in bone that is related in sequence to the cystatin family of thiol protease inhibitors. This suggests that Spp-24 could function to modulate the thiol protease activities known to be involved in bone turnover. It is also possible that the intact form of Spp-24 found in bone could be a precursor to a biologically active peptide that coordinates an aspect of bone turnover.

Cystatin-like domain; Cystatins are a family of cysteine protease inhibitors that occur mainly as single domain proteins. However some extracellular proteins such as kininogen, His-rich glycoprotein and fetuin also contain these domains.

Cystatin domain; Very diverse family. Attempts to define separate sub-families failed. Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. pfam00666 is related to this family but has not been included.
