Cystatin D is a 17kD member of the type 2 cystatin family of proteins. It is expressed in salivary gland, skin, prehypertrophic and hypertrophic chondrocytes. Within the context of endochondral ossification, it may both induce chondrocyte apoptosis and initiate the process of cartilage calcification. Although Cystatin D contains a key cystatin motif (Gln-x-Val-x-Gly), Cystatin D does not appear to inhibit cysteine proteases. Mouse Cystatin D is 148aa in length. It contains one cystatin-like domain aa39-145. There are two potential splice variants. One shows a deletion of aa84-121, while a second shows a Val substitution for aa122-148. Full-length mouse Cystatin D shares 78aa identity with rat Cystatin D. There appears to be no direct human counterpart to mouse Cystatin D, as both human cystatin-C and -D share less that 40% aa identity with mouse Cystatin D.
