Atr - ataxia telangiectasia and Rad3 related

Enables protein kinase activity. Involved in positive regulation of telomere maintenance via telomerase and replication fork processing. Acts upstream of or within several processes, including DNA damage checkpoint signaling; embryo implantation; and protein phosphorylation. Located in XY body. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; eye; and gonad. Used to study Seckel syndrome. Human ortholog(s) of this gene implicated in Seckel syndrome 1; adenoid cystic carcinoma; colon cancer; lung cancer; and pancreatic cancer. Orthologous to human ATR (ATR serine/threonine kinase).
