Autodegradation of the E3 ubiquitin ligase COP1

Reactome ID: R-HSA-349425

中文名称

E3 泛素连接酶 COP1 的自降解

通路描述

COP1 是负责严格调节 p53 丰度的几种 E3 泛素连接酶之一。在 DNA 损伤后,COP1 从 p53 解离,并通过涉及 ATM 磷酸化 COP1 在 Ser(387) 位点、自泛素化和蛋白酶体介导的降解的途径被无活性的自降解。COP1 的破坏导致 p53 的泛素化和降解被阻断(Dornan et al., 2006)。
英文描述
Autodegradation of the E3 ubiquitin ligase COP1 COP1 is one of several E3 ubiquitin ligases responsible for the tight regulation of p53 abundance. Following DNA damage, COP1 dissociates from p53 and is inactivated by autodegradation via a pathway involving ATM phosphorylation of COP1 on Ser(387), autoubiquitination and proteasome mediated degradation. Destruction of COP1 results in abrogation of the ubiquitination and degradation of p53 (Dornan et al., 2006).
