CDKN2B [ENSP00000276925]
cyclin-dependent kinase inhibitor 2B (p15, inhibits CDK4); 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
CDK4 [ENSP00000257904]
cyclin-dependent kinase 4; Probably involved in the control of the cell cycle
