Ligands: GTP Activity: Protein-glutamine gamma-glutamyltransferase, with EC number 2.3.2.13 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [TGM2_HUMAN] Catalyzes the cross-linking of proteins and the conjugation of polyamines to proteins. Publication Abstract from PubMed Transglutaminase2 (TG2) is a multi-functional protein involved in various cellular processes, including apoptosis, differentiation, wound healing, and angiogenesis. The malfunction of TG2 causes many human disease including inflammatory disease, celiac disease, neurodegenerative diseases, tissue fibrosis, and cancers. Protein cross-linking activity, which is representative of TG2, is activated by calcium ions and suppressed by GTP. Here, we elucidated the structure of TG2 in complex with its endogenous inhibitor, GTP. Our structure showed why GTP is the optimal nucleotide for interacting with and inhibiting TG2. In addition, sequence comparison provided information describing the evolutionary scenario of GTP usage for controlling the activity of TG2.
