SpletPCNA has recently been extensively reviewed for its role in DNA metabolism including DNA damage tolerance (DDT) and DNA damage repair (DDR) pathways [[12], [13], [14]]. To our knowledge, however, the influence of PCNA as a regulator of replication fork progression in the ALT pathway has not been discussed in the literature. Splet28. maj 2024 · p21Waf/CIP1 is a small unstructured protein that binds and inactivates cyclin-dependent kinases (CDKs). To this end, p21 levels increase following the activation of the p53 tumor suppressor. CDK inhibition by p21 triggers cell-cycle arrest in the G1 and G2 phases of the cell cycle. In the absence of exogenous insults causing replication stress, …
