The protein encoded by this gene, a nuclear protein involved in cell cycle progression, is phosphorylated by an enzyme that in humans is encoded by the CDK2 gene (cyclin A/cyclin-dependent kinase 2) during the S-phase of the cell cycle and possesses both activator and repressor activities.
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. Cyclin-dependent kinase 2, also known as cell division protein kinase 2, or Cdk2, is an enzyme that in humans is encoded by the CDK2 gene.
