CHEK1 anticorps (pSer280)

N° du produit ABIN363147

Détail du produit anti-CHEK1 anticorps

Antigène: CHEK1 (Checkpoint Kinase 1 (CHEK1))

Épitope: pSer280

Reactivité: Humain

Hôte: Lapin

Clonalité: Polyclonal

Conjugué: Cet anticorp CHEK1 est non-conjugé

Application: Western Blotting (WB)

Specificité: The antibody detects endogenous level of Chk1 only when phosphorylated at serine 280.

Purification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

Immunogène: Peptide sequence around phosphorylation site of pSer280 (V-T-S (p) -G-G) derived from Human Chk1. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.

Isotype: IgG

Sujet: Required for checkpoint mediated cell cycle arrest in response to DNA damage or the presence of unreplicated DNA. May also negatively regulate cell cycle progression during unperturbed cell cycles. Recognizes the substrate consensus sequence [R-X-X-S/T]. Binds to and phosphorylates CDC25A, CDC25B and CDC25C. Phosphorylation of CDC25A at 'Ser-178' and 'Thr-507' and phosphorylation of CDC25C at 'Ser-216' creates binding sites for 14-3-3 proteins which inhibit CDC25A and CDC25C. Phosphorylation of CDC25A at 'Ser-76', 'Ser-124', 'Ser-178', 'Ser-279' and 'Ser-293' promotes proteolysis of CDC25A. Inhibition of CDC25 activity leads to increased inhibitory tyrosine phosphorylation of CDK-cyclin complexes and blocks cell cycle progression. Binds to and phosphorylates RAD51 at 'Thr-309', which may enhance the association of RAD51 with chromatin and promote DNA repair by homologous recombination. Binds to and phosphorylates TLK1 at 'Ser-743', which prevents the TLK1-dependent phosphorylation of the chromatin assembly factor ASF1A. This may affect chromatin assembly during S phase or DNA repair. May also phosphorylate multiple sites within the C-terminus of TP53, which promotes activation of TP53 by acetylation and enhances suppression of cellular proliferation.
