Protein-glutamine gamma-glutamyltransferase K is an enzyme that in humans is encoded by the TGM1 gene.[1][2]

Keratinocyte transglutaminase is a transglutaminase enzyme.


A deficiency is associated with ichthyosis lamellaris.[3] Epidermal transglutaminase is the autoantigen, in humans, of dermatitis herpetiformis.
