Summary: Enables protein kinase activity. Involved in DNA metabolic process; positive regulation of DNA-templated DNA replication; and signal transduction in response to DNA damage. Located in nucleus. Used to study several diseases, including Seckel syndrome; ataxia telangiectasia; colon cancer; endometrial cancer; and non-Hodgkin lymphoma. Human ortholog(s) of this gene implicated in Seckel syndrome (multiple); gastrointestinal system cancer (multiple); lung cancer; and pancreatic cancer. Orthologous to human ATR (ATR serine/threonine kinase). [provided by Alliance of Genome Resources, Nov 2024]
