细胞周期调节是一个复杂过程,近年来这方面的研究取得了很大进展。在酵母中发现的Cdc2基因很重要,它是唯一在2个控制点起作用的cdc基因。本文主要介绍Cdc2分子的结构、作用以及与肿瘤和凋亡等方面的关系。 Cell cycle regulation is a complex process, and great progress has been made in this field in recent years. The Cdc2 gene found in yeast is important, and is the only cdc gene that works at two control points. This article describes the structure of Cdc2 molecules, the role and the relationship between tumor and apoptosis.
