TGM3 (Protein-glutamine gamma-glutamyltransferase E) is an enzyme. In the public catalogues the evidence so far is association rather than a proven role. Tied to Skin cancer and Basal cell carcinoma. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Catalyses 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 specialised component consisting of covalent cross-links of proteins beneath the plasma membrane of terminally differentiated keratinocytes. Catalyses small proline-rich proteins (SPRR1 and SPRR2) 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. Location: Cytoplasm (UniProt). Locus 20p13 (HGNC).
