This protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. Expression is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. P21CIP1 can interact with proliferating cell nuclear antigen (PCNA), a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein has been reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.4 ml \/ Rabbit","offer_id":49477882347800,"sku":"F48424-0.4ML","price":429.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_f0c05865-9671-4b7a-83fb-dd4116380e3c.jpg?v=1734502187","url":"https:\/\/danabiosci.com\/products\/f48424-0-4ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
