Glossaryp16 (p16INK4a)

inhibits cell division by regulating cyclin-dependent kinases

p16, also known as CDKN2A, is a protein that acts as a tumor suppressor by regulating the cell cycle. It inhibits cyclin-dependent kinases (CDKs), which are enzymes that promote cell division, thereby preventing uncontrolled cell growth that can lead to cancer.
