MEF2A (Acetyl-K403) polyclonal antibody

MEF2A is a member of the MEF2 (myocyte enhancer factor 2) family of transcription factors. In mammals, four MEF2A-related genes (MEF2A, MEF2B, MEF2C and MEF2D) encode proteins which exhibit significant amino acid sequence similarity within their DNA binding domains and to a lesser extent throughout the remaining proteins. The MEF2 family members were originally described as muscle-specific DNA binding proteins that recognize MEF2 motifs found within the promoters of many muscle-specific genes. Phosphorylation of MEF2A at Thr312 and Thr319 within the transcription activation domain by p38 MAP kinase enhances MEF2A-MEF2D heterodimer-dependent gene expression. On the other hand, apoptotic stimuli (e.g. neurotoxic insult) result in CDK5-dependent phosphorylation of MEF2A at Ser408 within the activation domain, inhibiting MEF2A pro-survival function.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 96% (by SDS-PAGE) .
