Progression through the cell cycle is regulated by numerous proteins, one of which is the cyclin-dependent kinase inhibitor, p21. A new study identifies a novel protein complex that stabilizes p21. The stability of this complex is critical in effecting the p53-mediated cell cycle checkpoint.
细胞周期的进程受多种蛋白质调控,其中之一是细胞周期蛋白依赖性激酶抑制剂p21。一项新研究鉴定出一种能使p21稳定的新型蛋白质复合物。该复合物的稳定性对于实现p53介导的细胞周期检查点至关重要。
