Functioning primarily as a molecular brake on the cell cycle, p21 binds to and inhibits the activity of cyclin-CDK complexes, particularly those involving CDK2, CDK4, and CDK6, thereby preventing the phosphorylation of the retinoblastoma protein (Rb) and arresting cell progression at the G1\/S checkpoint to allow time for DNA repair or to initiate senescence. Beyond its canonical role in cell cycle regulation, p21 exhibits complex, context-dependent functions by interacting with proliferating cell nuclear antigen (PCNA) to modulate DNA replication and repair mechanisms, while also influencing apoptosis through interactions with pro-apoptotic factors like ASK1 and caspases; notably, its expression can be induced via both p53-dependent and p53-independent pathways, making it a pivotal node in maintaining genomic stability and preventing tumorigenesis, although its overexpression in certain cancer contexts has been paradoxically associated with poor prognosis due to its potential anti-apoptotic effects.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"25μl","offer_id":43094335914059,"sku":"S0B6941-25μl","price":100.0,"currency_code":"USD","in_stock":true},{"title":"100μl","offer_id":43094335946827,"sku":"S0B6941-100μl","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/cae44de22bb04d4d8c372830727ee155.jpg?v=1788206527","url":"https:\/\/www.antbioinc.com\/products\/p21-waf1cip1-recombinant-rabbit-mab-s-3909-60-s0b6941","provider":"AntBio","version":"1.0","type":"link"}
