TGM2/Transglutaminase 2 蛋白, Mouse (His)

TGM2/Transglutaminase 2 protein, a calcium-dependent acyltransferase, catalyzes the formation of covalent bonds between peptide-bound glutamine and various primary amines, leading to the cross-linking or amination of proteins. Involved in diverse biological processes such as bone development, angiogenesis, wound healing, cellular differentiation, chromatin modification, and apoptosis, TGM2 acts as a protein-glutamine gamma-glutamyltransferase. It mediates the cross-linking of proteins, including ACO2, HSPB6, FN1, HMGB1, RAP1GDS1, SLC25A4/ANT1, SPP1, and WDR54. The protein cross-linking activity is inhibited under physiological conditions by GTP, and this inhibition is relieved by Ca(2+) in response to various stresses. In addition to its role in apoptosis by promoting cytoskeletal protein cross-linking and mediating the formation of extracellular matrix scaffolds, TGM2 can use monoamine substrates to catalyze diverse protein post-translational modifications. It plays a crucial role in chromatin organization by mediating serotonylation and dopaminylation of histone H3, contributing to neurotransmission-independent functions in ventral tegmental area (VTA) neurons. Furthermore, TGM2 acts as a signal transducer in alpha-1 adrenergic receptor-mediated stimulation of phospholipase C-delta (PLCD) activity, highlighting its involvement in signaling pathways beyond its acyltransferase activity. TGM2/Transglutaminase 2 Protein, Mouse (His) is the recombinant mouse-derived TGM2/Transglutaminase 2 protein, expressed by E. coli , with N-His labeled tag. The total length of TGM2/Transglutaminase 2 Protein, Mouse (His) is 685 a.a., with molecular weight of ~78.2 kDa.

TGM2/转谷氨酰胺酶 2 蛋白是一种钙依赖性酰基转移酶，催化肽结合的谷氨酰胺和各种伯胺之间形成共价键，导致蛋白质交联或胺化。 TGM2 充当蛋白质-谷氨酰胺 γ-谷氨酰转移酶，参与多种生物过程，如骨骼发育、血管生成、伤口愈合、细胞分化、染色质修饰和细胞凋亡。它介导蛋白质的交联，包括 ACO2、HSPB6、FN1、HMGB1、RAP1GDS1、SLC25A4/ANT1、SPP1 和 WDR54。在生理条件下，GTP 会抑制蛋白质交联活性，而在应对各种应激时，Ca(2+) 会缓解这种抑制。除了通过促进细胞骨架蛋白交联和介导细胞外基质支架的形成在细胞凋亡中发挥作用外，TGM2 还可以使用单胺底物催化多种蛋白质翻译后修饰。它通过介导组蛋白 H3 的血清素化和多巴胺化在染色质组织中发挥至关重要的作用，有助于腹侧被盖区 (VTA) 神经元的神经传递独立功能。此外，TGM2 在 α1 肾上腺素受体介导的磷脂酶 C-δ (PLCD) 活性刺激中充当信号转导器，突出显示其参与除酰基转移酶活性之外的信号通路。
