P16INK4a
Background
P16INK4a is a protein that inhibits the phosphorylating activity associated with the cdk4/6 - cyclin D complex and the counterparts, retinoblastoma protein (pRB) and the transciption factor E2F. Progression of the cell cycle is controlled by the pRB pathway and its ability to bind to the transciption factor E2F to block the transcription of genes that promote cell proliferation. The pRB pathway is critical for the maintenance of balance between cell cycle continuous and cell cycle rest.
