ATM siRNA sequences derived from siDESIGN, which analyzes potential sequences from cDNA with eight additional criteria as elaborated in Rational siRNA Design for RNA Interference, Reynolds, A. et al. (2004), Nature Biotechnology 22, 326-330) and then performing a Nucleotide-Nucleotide BLAST (BLASTN) homology search of each to determine whether the target sequence has similarities in other genes:

Ataxia Telangiectasia Mutated (ATM)
(Includes Complementation Groups A, C and D)
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. Two transcript variants encoding different isoforms have been found for this gene.
