Protein
Protein-glutamine gamma-glutamyltransferase E
Gene
Tgm3, Tgase3
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the calcium-dependent formation of isopeptide cross-links between glutamine and lysine residues in various proteins, as well as the conjugation of polyamines to proteins. Involved in the formation of the cornified envelope (CE), a specialized component consisting of covalent cross-links of proteins beneath the plasma membrane of terminally differentiated keratinocytes. Catalyzes small proline-rich proteins and LOR cross-linking to form small interchain oligomers, which are further cross-linked by TGM1 onto the growing CE scaffold. In hair follicles, involved in cross-linking structural proteins to hardening the inner root sheath By similarity.

Catalytic activityi

Protein glutamine + alkylamine = protein N(5)-alkylglutamine + NH3.

Cofactori

Binds 3 calcium ions per subunit. Binds 1 calcium ion as a zymogen, and binds 2 more calcium ions, or other divalent metal cations, after proteolytic processing By similarity.
