Protein ubiquitination requires the concerted action of the E1, E2, and E3 ubiquitin-conjugating enzymes. Ubiquitin is first activated through ATP-dependent formation of a thiol ester with ubiquitin-activating enzyme E1. The activated ubiquitin is then transferred to a thiol group of ubiquitin-carrier enzyme E2. The final step is the transfer of ubiquitin from E2 to an ε-amino group of the target protein lysine residue, which is mediated by ubiquitin-ligase enzyme E3 (1).

Ubiquitin conjugating-enzyme 2T (UBE2T) is an E2 family member responsible for the ATP-dependent ubiquitin tagging of target proteins for degradation. Research studies indicate that UBE2T plays an important role in the Fanconi anemia pathway and that UBE2T expression is required for normal DNA repair through this pathway. Interaction between UBE2T and FANCL appears to stimulate UBE2T auto monoubiquitination, leading to UBE2T inactivation and negative regulation of the Fanconi anemia pathway (2-4). Additional research details upregulation of UBE2T expression in breast cancer cells and certain lung carcinomas, suggesting a possible involvement in these malignancies (5,6).

蛋白泛素化作用需要E1, E2, 和E3泛素-连接酶的协同作用。泛素最先通过具有硫酯的泛素激活酶E1通过ATP-依赖形式活化。活化的泛素然后通过含有巯基的泛素载体蛋白E2转运。最后从E2的泛素转运到含有ε-氨基的赖氨酸残疾靶蛋白,这由泛素连接酶E3介导(1)。

UBE2T是E2家族成员,负责ATP依赖性的蛋白质降解。研究发现UBE2T在范科尼贫血中扮演重要角色,并且通过这种途径参与一般的DNA修复过程。UBE2T与FANCL的相互作用激活UBE2T自单泛素化,导致UBE2T的失活和范科尼贫血的负调控(2-4)。另外研究表明, 在乳腺癌和一些肺癌中UBE2T的表达上调,表明其可能参与肿瘤恶化(5,6)。
