Cyclin-dependent kinase 6 (CDK6)

Phosphorylates pRB/RB1 and NPM1. Interacts with D-type G1 cyclins during interphase in G1 to form a pRB/RB1 kinase and controls the entry into the cell cycle.

Involved in initiation and maintenance of cell cycle exit during cell differentiation; prevents cell proliferation and regulates negatively cell differentiation, but is necessary for the proliferation of specific cell types (e.g.
