UniProtKB - D4A5U3 (TGM3_RAT)
Protein
Protein-glutamine gamma-glutamyltransferase E
Gene
Tgm3
Organism
Rattus norvegicus (Rat)
Status
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).By similarity

Cofactori
Ca2+By similarityNote: Binds 3 Ca2+ cations per subunit. Binds 1 Ca2+ as a zymogen, and binds 2 more Ca2+ cations, or other divalent metal cations, after proteolytic processing.By similarity
