MYBL2
View/Edit Human | View/Edit Mouse |
Myb-related protein B is a protein that in humans is encoded by the MYBL2 gene.[3]
Function
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. Transcript variants may exist for this gene, but their full-length natures have not been determined.[4]
Interactions
MYBL2 has been shown to interact with:
- CDK9,[5]
- CREB-binding protein,[6]
- Cyclin A1,[7]
- Cyclin-dependent kinase inhibitor 1C[8]
- EP300,[9]
- PARP1,[10] and
- Retinoblastoma-like protein 1.[8][11]
