CDKN1A binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at the G1 phase. The expression of CDKN1A is induced by wild-type but not mutant p53 protein, through which CDKN1A mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. CDKN1A can interact with proliferating cell nuclear antigen (PCNA), and plays a regulatory role in S phase DNA replication and DNA damage repair. CDKN1A was 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. Two alternatively spliced variants, which encode an identical protein, have been reported.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human\nCited Reactivity: human\nHost \/ Isotype: Rabbit \/ IgG\nClass: Recombinant\nType: Antibody\nImmunogen: CatNo: Ag0368 Product name: Recombinant human P21;CDKN1A protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 1-149 aa of BC000275 Sequence: MSEPAGDVRQNPCGSKACRRLFGPVDSEQLSRDCDALMAGCIQEARERWNFDFVTETPLEGDFAWERVRGLGLPKLYLPTGPRRGRDELGGGRRPGTSPALLQGTAEEDHVDLSLSCTLVPRSGEQAEGSPGGPGDSQGRKRRQTSMTD Predict reactive species\nFull Name: cyclin-dependent kinase inhibitor 1A (p21, Cip1)\nCalculated Molecular Weight: 18 kDa\nObserved Molecular Weight: 21 kDa\nGenBank Accession Number: BC000275\nGene Symbol: p21\nGene ID (NCBI): 1026\nRRID: AB_3086498\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Protein A purification\nUNIPROT ID: P38936\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
