In this issue of Molecular Cell, Guo et al. (2012) demonstrate how a series of sequential posttranslational modifications, phosphorylation, sumoylation, and ubiquitylation, cooperate to target human flap endonuclease FEN1 to degradation by the proteasome at the end of S phase.
在本期《分子细胞》中,郭等人(2012)展示了一系列连续的翻译后修饰(磷酸化、SUMO 化和泛素化)如何协同作用,将人类的核酸内切酶 FEN1 靶向到 S 期结束时的蛋白酶体降解。
