INK4

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 p16(INK4a), p15(INK4b), p18(INK4c), and p19(INK4d), block the progression of the cell cycle by binding to either Cdk4 or Cdk6 and inhibiting the action of cyclin D. These INK4 proteins share a similar structure dominated by several ankyrin repeats. The INK4 proteins are commonly lost or inactivated by mutations in diverse types of cancer, and they represent established or candidate tumor suppressors. Apart from their capacity to arrest cells in the G1-phase of the cell cycle they have been shown to participate in an increasing number of cellular processes. Extensive studies, over the past few years, uncover the involvement of INK4 proteins in senescence, apoptosis, DNA repair, and multistep oncogenesis.[1]
