[https://www.uniprot.org/uniprot/ATR_HUMAN ATR_HUMAN] Familial cutaneous telangiectasia and oropharyngeal predisposition cancer syndrome;Seckel syndrome.

== Function == | |||
[https://www.uniprot.org/uniprot/ATR_HUMAN ATR_HUMAN] 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.<ref>PMID:10597277</ref> <ref>PMID:10608806</ref> <ref>PMID:10859164</ref> <ref>PMID:11114888</ref> <ref>PMID:11418864</ref> <ref>PMID:11673449</ref> <ref>PMID:11721054</ref> <ref>PMID:11865061</ref> <ref>PMID:12526805</ref> <ref>PMID:12791985</ref> <ref>PMID:12814551</ref> <ref>PMID:14657349</ref> <ref>PMID:14729973</ref> <ref>PMID:14742437</ref> <ref>PMID:15210935</ref> <ref>PMID:15314022</ref> <ref>PMID:15496423</ref> <ref>PMID:16260606</ref> <ref>PMID:21144835</ref> <ref>PMID:27723717</ref> <ref>PMID:27723720</ref> <ref>PMID:9427750</ref> <ref>PMID:9636169</ref> <ref>PMID:9925639</ref> | |||
