molecule that halts or slows down cell division

A cell cycle inhibitor, also known as a cell cycle suppressor or cell cycle regulator, is a molecule that can halt or slow down the process of cell division. These inhibitors play a crucial role in controlling cell growth and ensuring that cells do not divide uncontrollably, which is important for preventing conditions like cancer. For example, proteins like p21 and p27 are well-known cell cycle inhibitors that can stop the cell cycle at specific checkpoints, allowing for DNA repair or triggering cell death if the damage is irreparable.
