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.

Immunogen

Linear peptide corresponding to human ATM/ATR (Thr1989).

Purpose: PARP inhibition (PARPi) has modest clinical activity in recurrent BRCA-mutant (BRCAMUT) high-grade serous ovarian cancers (HGSOC). We hypothesized that PARPi increases dependence on ATR/CHK1 such that combination PARPi with ATR/CHK1 blockade results in increased cell death and tumor regression.Experimental

Oncogene-induced replication stress, for instance as a result of Cyclin E1 overexpression, causes genomic instability and has been linked to tumorigenesis. To survive high levels of replication stress, tumors depend on pathways to deal with these DNA lesions, which represent

CCNE1-amplified ovarian cancers (OVCAs) and endometrial cancers (EMCAs) are associated with platinum resistance and poor survival, representing a clinically unmet need. We hypothesized that dysregulated cell-cycle progression promoted by CCNE1 overexpression would lead to increased sensitivity to low-dose WEE1 inhibition
