Anti-phospho ATM/ATR (Thr1989) Antibody (C15-1317-169)

General description

The Ataxia-Telangiectasia and Rad3 related kinase (ATR) is a nuclear serine/threonine kinase that is part of the "first-response" system to DNA damage induced by a wide variety of factors including double-stranded breaks and replication stress. The localization of ATR to sites of DNA damage is aided by the Replication Protein A (RPA). Phospho - ATR (Ser428) targets a number of proteins including BRCA1, WRN, CHEK1, MCM2, and p53/TP53, and coordinates signaling pathways involved in DNA repair and apoptosis. ATR may also be involved in the phosphorylation of the histone H2A.X after replication stress, an early marker of DNA damage. However, ATR also mediates DNA replication and fork stability in normal cell cycles by activation of Chk1. Defective ATR contributes to Seckel syndrome type 1.
