We know how important it is to your research to have access to antibodies specific for your model. As it is often impossible to know which antibody will work best for a specific sample and application, we now offer SuperNovus Packs. These packs include different antibodies to the same protein to give you the ability to decide for yourself. The SuperNovus Packs are all offered at a discount price compared to purchasing each antibody individually. Ataxia-telangiectasia (A-T) is a recessive childhood disease caused by mutations in the ATM (AT-mutated) gene. Symptoms include neurological abnormalities that cause unsteady posture, dilated blood vessels, infertility, radiation sensitivity, immune deficiencies and lymphoid malignancies. It appears that the diverse defects seen in ATM null mammals are manifestations of disparate signal transduction defects. The ATM protein is related to a family of proteins through a c-terminal phoshatidylinositol 3-kinase (PI3-kinase) domain. Members of the PI3-kinase family of proteins are involved in cell cycle control, DNA replication, recombination and repair. ATM also shares sequence homology with portions of the yeast RAD3 gene. The main role of ATM appears to be induction of a DNA-damage control pathway in response to genotoxic insults, such as ionizing radiation or anti-tumor medications and the programmed DNA breaks of meiosis.
