Product Specific Information
This antibody detects endogenous levels of Chk1 only when phosphorylated at Serine 280.
Target Information
CHEK1 (CHK1) is a serine/threonine protein kinase involved in preventing replication when DNA integrity is compromised. It serves as a key mediator in the DNA damage-induced checkpoint network, ensuring genomic stability under genotoxic stress.
When CHK1 inhibition abrogates the G2 or S checkpoint, p53-deficient cancer cells undergo mitotic catastrophe and apoptosis, whereas normal cells remain arrested in G1.
Thus, CHK1 is an attractive therapeutic target for cancer treatment, particularly in p53-deficient tumors.
