Inhibition of replication initiation of damaged DNA by RB1/E2F1

Reactome ID: R-HSA-113501

中文名称

RB1/E2F1 对受损 DNA 复制起始的抑制

通路描述

在细胞周期的 S 期,RB1 由 PP2A 蛋白磷酸酶复合物去磷酸化。未磷酸化的 RB1 与 S 期中的 DNA 损伤位点结合,阻止这些位点处 DNA 复制的起始(Knudsen 等人,2000;Avni 等人,2003)。
英文描述
Inhibition of replication initiation of damaged DNA by RB1/E2F1 During S phase of the cell cycle, RB1 is dephosphorylated by the PP2A protein phosphatase complex. Unphosphorylated RB1 associates with DNA damage sites in S phase, preventing initiation of DNA replication from these sites (Knudsen et al. 2000, Avni et al. 2003).
