pfam10511: Cementoin 
Trappin protein transglutaminase binding domain
Trappin-2, itself a protease inhibitor, has this unique N-terminal domain that enables it to become cross-linked to extracellular matrix proteins by transglutaminase. This domain contains several repeated motifs with the the consensus sequence Gly-Gln-Asp-Pro-Val-Lys, and these together can anchor the whole molecule to extracellular matrix proteins, such as laminin, fibronectin, beta-crystallin, collagen IV, fibrinogen, and elastin, by transglutaminase-catalyzed cross-links. The whole domain is rich in glutamine and lysine, thus allowing and transglutaminase(s) to catalyze the formation of an intermolecular epsilon-(gamma-glutamyl)lysine isopeptide bond. Cementoin is associated with the WAP family, pfam00095, at the C-terminus.
