  • Number of PDB entries for P42771: 4
 
Function
Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6. This inhibits their ability to interact with cyclins D and to phosphorylate the retinoblastoma protein. (data source: UniProt  )
Subunit structure
Heterodimer with CDK4 or CDK6. Predominant p16 complexes contained CDK6. Interacts with CDK4 (both 'T-172'-phosphorylated and non-phosphorylated forms); the interaction inhibits cyclin D-CDK4 kinase activity. Interacts with ISCO2. (data source: UniProt  )
