General description

Monoclonal Anti-ATM (mouse IgG1 isotype) is derived from the hybridoma MAT3-4G10/8 produced by the fusion of mouse myeloma cells (NSO) and splenocytes from BALB/c mice immunized with a peptide.

Specificity

Monoclonal Anti-ATM antibody reacts specifically with mouse and human ATM.

Immunogen

peptide spanning positions 1967-1988 of mouse ATM containing a cysteine at its NH2 terminus coupled to KLH.

Application

Monoclonal Anti-ATM antibody can be used in immunoblotting , ELISA and immunoprecipitation.

Biochem/physiol Actions

Anti-Ataxia-Telangiectasia Mutated (ATM) is responsible for the activation and stabilization of p53 in response to double-strand break (DSB). ATM phosphorylates p53 directly on Ser15 and concomitantly activates other kinases that phosphorylate the same molecule on additional sites. Furthermore, human homolog of double minute 2 (Hdm2) is phosphorylated by ATM on Ser395 and this phosphorylation inhibits Hdm2-mediated degradation of p53.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

Ataxia-telangiectasia (A-T) is an autosomal recessive chromosome breakage disorder caused by mutations in the ATM gene. Typically, it presents in early childhood with progressive cerebellar dysfunction along with immunodeficiency and oculocutaneous telangiectasia. An increased risk of malignancy is also associated
