MeSH definition : A cyclin-dependent kinase inhibitor that coordinates the activation of CYCLIN and
CYCLIN-DEPENDENT KINASES during the CELL CYCLE. It interacts with active CYCLIN D
complexed to CYCLIN-DEPENDENT KINASE 4 in proliferating cells, while in arrested cells
it binds and inhibits CYCLIN E complexed to CYCLIN-DEPENDENT KINASE 2.;
