FZR1(也称为Cdh1)是细胞周期调控中一个重要的基因,属于后期促进复合物/环体(APC/C)的激活子亚家族。它的主要功能是通过调控APC/C的活性,参与细胞周期的有序进行,特别是在有丝分裂的退出和G1期的维持中起关键作用。FZR1通过促进特定周期蛋白(如Cyclin B和Cyclin A)的泛素化降解,确保细胞周期的正常过渡。此外,FZR1还在DNA损伤修复、神经元发育和代谢调控等过程中发挥作用。FZR1的突变或表达异常可能导致细胞周期紊乱,与多种癌症(如乳腺癌、肺癌和结直肠癌)的发生密切相关。FZR1的过表达可能导致细胞周期停滞在G1期,抑制细胞增殖,而降低表达则可能引起细胞周期失控,促进肿瘤发生。FZR1属于APC/C激活子家族,该家族成员(如CDC20和FZR1)的共同特点是能够特异性识别并结合APC/C,调控其底物的泛素化降解,从而影响细胞周期进程和其他生物学过程。FZR1的功能多样性使其在细胞稳态维持和疾病发展中扮演重要角色。
