MYBL2（MYB proto-oncogene like 2），癌症关联基因，基因ID：4605，该基因编码的蛋白是参与细胞周期进程的核蛋白，属于MYB家族转录因子基因编码蛋白在细胞周期的S期被细胞周期蛋白A/cyclin依赖性激酶2磷酸化，具有激活和抑制活性它已被证明能激活细胞分裂周期2、细胞周期蛋白D1和胰岛素样生长因子结合蛋白5基因已经发现了两个编码不同亚型的转录变体。[由RefSeq提供，2013年7月]The protein encoded by this gene， a member of the MYB family of transcription factor genes， is a nuclear protein involved in cell cycle progression. The encoded protein is phosphorylated by cyclin A/cyclin-dependent kinase 2 during the S-phase of the cell cycle and possesses both activator and repressor activities. It has been shown to activate the cell division cycle 2， cyclin D1， and insulin-like growth factor-binding protein 5 genes. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq， Jul 2013]。
