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]
Forensic Context
A study in human trauma patients demonstrated that the MYBL2 mRNA was significantly downregulated in circulating CD3+ T cells during the injury stage compared to the recovery stage [Rau et al. DOI:10.2147/JIR.S375881].
