Che-1 (AATF) (Ser477) Antibody

Product Specifications

Background

Che-1, also known as AATF (apoptosis-antagonizing transcription factor), is a RNA polymerase II-binding protein involved in regulating the transcription factor E2F and promoting cell cycle progression (Burgdorf et al., 2004) . It has been suggested that Che-1 may act as a neuroprotective factor against Abeta-induced apoptosis by suppressing the production of reactive oxidative species (Xie et al., 2004) . The checkpoint kinase Chk2 has been shown to phosphorylate Che-1 at Ser-477 contributing to the maintenance of the G2/M checkpoint induced by DNA damage (Bruno et al., 2006) .

Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser477 of human Che-1, conjugated to keyhole limpet hemocyanin (KLH) .

Applications

Purification

Antigen Affinity purification from Pooled whole antiserum

Concentration

Lot Dependent

Dilution

WB (1:300-5000)

Buffer

10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Modification

Phosphorylation

Storage Conditions

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Specificity

Specific for endogenous levels of the ~66 kDa Che-1 protein phosphorylated at Ser477. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.
