Serine/threonine protein kinase which activates checkpoint signaling upon genotoxic stresses such as ionizing radiation(IR), ultraviolet light(UV), or DNA replication stalling, thereby acting as a DNA damage sensor. Recognizes the substrate consensus sequence (ST)-Q. Phosphorylates BRCA1, CHEK1, MCM2, RAD17, RPA2, SMC1 and p53/TP53, which collectively inhibit DNA replication and mitosis and promote DNA repair, recombination and apoptosis. Phosphorylates 'Ser-139' of histone variant H2AX/H2AFX at sites of DNA damage, thereby regulating DNA damage response mechanism. Required for FANCD2 ubiquitination. Critical for maintenance of fragile site stability and efficient regulation of centrosome duplication.
