CDK5 [ENSP00000297518]
 
cyclin-dependent kinase 5; Probably involved in the control of the cell cycle. Interacts with D1 and D3-type G1 cyclins. Can phosphorylate histone H1, tau, MAP2 and NF-H and NF-M. Also interacts with p35 which activates the kinase
CDKN1A [ENSP00000244741]
 
cyclin-dependent kinase inhibitor 1A (p21, Cip1); May be the important intermediate by which p53 mediates its role as an inhibitor of cellular proliferation in response to DNA damage. Binds to and inhibits cyclin-dependent kinase activity, preventing phosphorylation of critical cyclin-dependent kinase substrates and blocking cell cycle progression
