It functions in stoichiometric relationships forming heterotrimeric complexes with cyclins and cyclin-dependent kinases. In association with CDK2 complexes, it serves to inhibit kinase activity and block progression through G1\/S (1). However, p21 may also enhance assembly and activity in complexes of CDK4 or CDK6 and cyclin D (2). The carboxy-terminal region of p21 is sufficient to bind and inhibit PCNA, a subunit of DNA polymerase, and may coordinate DNA replication with cell cycle progression (3). Upon UV damage or during cell cycle stages when cdc2\/cyclin B or CDK2\/cyclin A are active, p53 is phosphorylated and upregulates p21 transcription via a p53-responsive element (4). Protein levels of p21 are downregulated through ubiquitination and proteasomal degradation (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCAP20; CDK-interacting protein 1; CDK-interaction protein 1; CDKN1; CDKN1A; CDN1A; CIP1; cyclin dependent kinase inhibitor 1A; Cyclin-dependent kinase inhibitor 1; cyclin-dependent kinase inhibitor 1A (p21, Cip1); DNA synthesis inhibitor; MDA-6; MDA6; melanoma differentiation associated protein 6; Melanoma differentiation-associated protein 6; p21; p21CIP1; p21Cip1\/Waf1; PIC1; SDI1; WAF1; wild-type p53-activated fragment 1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk\nSENSITIVITY: Endogenous\nMW (kDa): 21\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798061011113,"sku":"2947L","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2947l","provider":"Iright","version":"1.0","type":"link"}
