描述

In summary, TGM2 is a multifunctional enzyme that plays crucial roles in various cellular processes. It acts as a protein-glutamine gamma-glutamyl transferase, mediating the cross-linking of proteins involved in cellular functions. TGM2/Transglutaminase 2 Protein, Human (sf9, His, solution) is the recombinant human-derived TGM2/Transglutaminase 2, expressed by Sf9 insect cells , with N-His labeled tag. ,

研究背景

转谷氨酰胺酶 2 (TGM2) 是一种钙依赖性酰基转移酶,可促进肽结合的谷氨酰胺和各种伯胺之间形成共价键,从而导致蛋白质交联或胺化。它在多种生物过程中发挥着至关重要的作用,包括骨骼发育、血管生成、伤口愈合、细胞分化、染色质修饰和细胞凋亡。TGM2 通过介导参与重要细胞功能的各种蛋白质的交联,充当蛋白质-谷氨酰胺 γ-谷氨酰转移酶。在生理条件下,其蛋白质交联活性被GTP抑制,并在应激过程中缓解对Ca(2+)反应的抑制。当分泌时,TGM2 催化细胞外基质蛋白的交联,形成稳定的支架。在细胞凋亡过程中,TGM2 通过促进细胞骨架蛋白的交联来促进细胞质的浓缩,并介导支架的不可逆形成,从而在吞噬作用清除之前稳定垂死的细胞,从而防止有害的细胞内成分泄漏。此外,TGM2 执行多种蛋白质翻译后修饰,包括将血清素、多巴胺、去甲肾上腺素或组胺氨化为谷氨酰胺残基,分别产生蛋白质血清素化、多巴胺化、去甲肾上腺素化或组胺化。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关键作用。此外,TGM2 在腹侧被盖区 (VTA) 神经元中充当核多巴胺神经传递独立作用的介导者,调节奖励系统中与复发相关的转录可塑性。它还通过介导血清素化和随后的 ATP2A2/SERCA2 失活来调节静脉重塑。此外,TGM2 作为蛋白质脱酰胺酶,将特定的谷氨酰胺残基转化为谷氨酸,并且可以作为异肽酶裂解先前形成的交联。它还可以独立于其酰基转移酶活性参与信号转导通路,在 α-1 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,并且是将 α-1 肾上腺素激动剂与刺激偶联所必需的磷酸肌醇脂质代谢的影响。TGM2 具有细胞毒活性,可独立于其酰基转移酶活性诱导细胞凋亡。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
