General description

ATM is a 370 kDa nuclear phosphoprotein involved in the autosomal recessive disease Ataxia Telangiectasia (AT). Ataxia telangiectasia (AT) is a debilitating neurodegenerative disease that occurs early in childhood, resulting in ataxic movements and speech defects caused by cerebellar degeneration. The underlying cause of the disease is a biochemical dysfunction in the cellular response to specific types of DNA damage, correlated with mutations in the protein kinase ATM (Ataxia telangiectasia mutated). ATM not only is key in the signaling cascade that responds to DNA double-stranded breaks, but it also controls cell-cycle checkpoints and is therefore important in cancer prevention.

Specificity

Reacts with ATM Kinase phosphorylated at serine 1981. Clone 10H11.E12 is covered by US patent No. 6,916,627 and 7,108,992.

Immunogen

Epitope: phosphoSer1981
Synthetic peptide corresponding to amino acids 1974-1988 of human ATM (SLAFEEG[pS]QSTTISS).

Application

Anti-ATM Antibody, phosphoSer1981, clone 10H11.E12 is a Mouse Monoclonal Antibody for detection of ATM also known as Ataxia Telangiectasia Mutated & has been validated in IP, WB, ICC.

The alternative lengthening of telomeres (ALT) mechanism allows cancer cells to escape senescence and apoptosis in the absence of active telomerase. A characteristic feature of this pathway is the assembly of ALT-associated promyelocytic leukemia (PML) nuclear bodies (APBs) at telomeres.
