The antibody detects endogenous level of ATF-2 only whenphosphorylated at threonine 73 or 55.
纯化方法
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific phosphopeptide. The antibody against non-phosphopeptide was removedby chromatography using non-phosphopeptide corresponding to the phosphorylation site.
免疫原
Peptide sequence around phosphorylation site of pThr73 or 55 (T-P-T (p) -R-F) derived from Human ATF2. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.
Transcriptional activator, probably constitutive, which binds to the cAMP-responsive element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Interaction with JUN redirects JUN to bind to CRES preferentially over the 12-O-tetradecanoylphorbol-13-acetate response elements (TRES) as part of an ATF2-c-Jun complex.
