Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

NPAT (HGNC:7896): (nuclear protein, coactivator of histone transcription) Enables protein C-terminus binding activity; transcription coactivator activity; and transcription corepressor activity. Involved in positive regulation of transcription by RNA polymerase II and regulation of transcription involved in G1/S transition of mitotic cell cycle. Located in Cajal body; Gemini of coiled bodies; and cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
