Checkpoint proteins play a key element in the regulation of the cell cycle. Checkpoints are made up of composites of protein kinases and adaptor proteins that are relevant for the integrity of the cell division process.

Examples are p53 that plays a role in halting the cell cycle in the G1 and has role in cell apoptosis. The ATM protein is involved in detecting double strand breaks in DNA and MAD can block entry to anaphase in cell division.
