Summary: Enables histone kinase activity. Involved in several processes, including chromosome organization; negative regulation of mitotic cell cycle phase transition; and photoreceptor cell maintenance. Located in nucleus. Used to study ataxia telangiectasia. Human ortholog(s) of this gene implicated in several diseases, including breast cancer (multiple); endocrine gland cancer (multiple); lung carcinoma (multiple); neurodegenerative disease (multiple); and senile cataract. Orthologous to human ATM (ATM serine/threonine kinase). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

our data indicate that ATR and ATM are both needed for intestinal stem cell maintenance and proliferation; ATR seems to play a bigger role than does ATM.
