Polo样激酶1(Plk1)是一类广泛存在于真核细胞中的丝氨酸/苏氨酸激酶,是细胞有丝分裂期的关键调控因子.在有丝分裂的不同时期,Plk1在细胞中的定位不同,并与不同的底物相互作用,从而具有多种生物学功能.文章对Plk1在细胞有丝分裂各个时期的功能作一综述.
Polo-like kinase 1 (Plk1) is a serine/threonine kinase that is widely expressed in eukaryotic cells and a key regulator of the cell mitosis.During different stages of mitosis,the locations of Plk1 in cells are different,and can interaction with different substrates,thus it has many biological functions.This article focuses on the functions of Plk1 in different mitotic stages.
