The atl-1 gene encodes a large, 2514-residue protein of the ATM family, homologous to human AT (OMIM:208900, mutated in ataxia telangiectasia); the C-terminal sequence of ATL-1 contains a PI-3 kinase-like domain; ATL-1 is required for survival through early embryogenesis and normal chromosomal segregation; atl-1 is expressed in both the mitotic and meiotic cells of adult gonads.
Predicted to enable 1-phosphatidylinositol-3-kinase activity and protein serine/threonine kinase activity. Involved in DNA damage checkpoint signaling; embryo development; and meiotic chromosome segregation. Located in nucleus. Expressed in gonad. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; Seckel syndrome 1; gastrointestinal system cancer (multiple); and pancreatic cancer. Is an ortholog of human ATR (ATR serine/threonine kinase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
