Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

Show »« Hide

Transglutaminases catalyse an acyl transferase reaction of γ-carboxamide groups of glutamine residues (on the donor peptide) with ε-amino groups of lysine residues (on an acceptor peptide) which creates a crosslink between the two proteins. This enzymatic activity is calcium-dependent, and the bonds that are formed are highly resistant to proteolytic cleavage. Nine human transglutaminase-encoding genes have been identified, but only 8 are known to be enzymatically active.
