INK4 proteins, a family of mammalian CDK inhibitors with novel biological functions
The cyclin D-Cdk4-6/INK4/Rb/E2F pathway plays a key role in controlling cell growth by integrating multiple mitogenic and antimitogenic stimuli. The members of INK4 family, comprising p16INK4a, p15INK4b, p18INK4c, and p19INK4d, block the progression of the cell cycle by binding to either Cdk4 or Cdk...
