GRAIL (gene related to anergy in lymphocytes, also known as RNF128), an ubiquitin-protein ligase (E3), utilizes a unique single transmembrane protein with a split-function motif, and is an important gatekeeper of T-cell unresponsiveness. Although it may play a role in other CD4 T-cell functions including activation, survival and differentiation, GRAIL is most well characterized as a negative regulator of T-cell receptor responsiveness and cytokine production. Here, we review the recent literature on this remarkable E3 in the regulation of human and mouse CD4 T-cell unresponsiveness.
GRAL(淋巴细胞无反应性相关基因,也称为 RNF128),一种泛素蛋白连接酶(E3),利用具有分裂功能基序的独特单次跨膜蛋白,是 T 细胞无反应性的重要守门员。虽然它可能在其他 CD4 T 细胞功能中发挥作用,包括激活、存活和分化,但 GRAIL 作为 T 细胞受体反应性和细胞因子产生的负调节剂最为突出。在这里,我们回顾了关于这种调节人类和小鼠 CD4 T 细胞无反应性的 E3 的最新文献。
