Western Blotting

Western blot analysis of extracts from COS cells, untreated or UV-treated, using Phospho-(Ser/Thr) ATM/ATR Substrate Antibody.
Western Blotting

Western blot analysis of yeast cell extracts, untreated or treated with 4-NQO, a potent activator of ATM/ATR orthologues, using Phospho-(Ser/Thr) ATM/ATR Substrate Antibody.
IP

Western blot analysis of immunoprecipitated protein from Chk2-transfected and UV-treated COS cells, using Chk2 antibody for immunoprecipitation and Phospho-(Ser/Thr) ATM/ATR Substrate Antibody for immunoblotting.
IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded HT-29 cells, untreated (left) or treated (right) with UV (upper) or doxorubicin (lower), using Phospho-(Ser/Thr) ATM/ATR Substrate Antibody.
ELISA-Peptide

Phospho-(Ser/Thr) ATM/ATR Substrate Antibody ELISA Assay: Signal-to-noise ratio of phospho- versus nonphospho-peptides. (S* or T* denote phosphorylated serine or threonine.)
Ataxia telangiectasia mutated kinase (ATM) and ataxia telangiectasia and Rad3-related kinase (ATR) are related kinases that regulate cell cycle checkpoints and DNA repair (1). The identified substrates for ATM are p53, p95/NBS1, MDM2, Chk2, BRCA1, CtIP, 4E-BP1, and Chk1 (1,2) The essential requirement for the substrates of ATM/ATR is S*/T*Q. Hydrophobic amino acids at positions -3 and -1, and negatively charged amino acids at position +1 are positive determinants for substrate recognition by these kinases. Positively charged residues surrounding the S*/T*Q are negative determinants for substrate phosphorylation (3). The complex phenotype of AT cells suggests that it likely has additional substrates (3). To better understand the kinase and identify substrates for ATM and the related kinase ATR, CST has developed antibodies that recognize phosphorylated serine or threonine in the S*/T*Q motif.
