Scientific Data Images for Human Chk2 Antibody

Detection of Human Chk2 antibody by Western Blot.

Detection of Human Chk2 by Western Blot.

Western blot shows lysates of MDA-MB-468 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human Chk2 Monoclonal Antibody (Catalog # MAB1358) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Chk2 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Chk2

Serine/threonine-protein kinase Chk2 (CHEK2) is a 65 kDa member of Serine/threonine-protein kinase family of proteins. Chk2 regulates cell cycle checkpoint arrest through phosphorylation of CDC25A, CDC25B and CDC25C. Inhibition of CDC25 phosphatase activity leads to increased inhibitory tyrosine phosphorylation of CDK-cyclin complexes and blocks cell cycle progression. Chk2 is required for checkpoint-mediated cell cycle arrest, activation of DNA repair and apoptosis in response to the presence of DNA double-strand breaks.Existence of multiple splice variants of Chk2 is predicted. Human Chk2 shares 86% aa sequence identity with mouse Chk2.
