Protein methylation

Reactome ID: R-HSA-8876725

中文名称

细胞周期

通路描述

细胞周期的进行是通过一系列可重复的事件完成的,包括 DNA 复制(S 期)和有丝分裂(M 期),这两者之间由称为 G1 和 G2 的间隙期隔开。细胞周期各阶段的进展由依赖蛋白激酶(CDKs)调节,每个 CDK 由催化 CDK 亚基和激活的 cyclin 亚基组成。CDKs 通过调节关键底物的活性来调节细胞周期的进展。CDKs 的下游靶标包括转录因子 E2F 及其调节因子 Rb。细胞周期特定点精确的 CDKs 激活和失活对于有序细胞分裂是必需的。细胞周期负调节的 CDK 抑制剂(CKIs),如 p16Ink4a、p15Ink4b、p27Kip1 和 p21Cip1,参与 CDK 活性的负调节,从而提供细胞周期负调节的途径。
英文描述
Protein methylation Methylation of lysine (Lys) and arginine (Arg) residues on non-histone proteins is a prevalent post-translational modification and important regulator of cellular signal transduction pathways including MAPK, WNT, BMP, Hippo and JAK–STAT. Crosstalk between methylation and other types of post-translational modifications and between histone and non-histone protein methylation is frequent, affecting cellular functions such as chromatin remodelling, gene transcription, protein synthesis, signal transduction and DNA repair (Biggar & Li 2015).
