Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Mouse.
Specificity / Sensitivity
Phospho-MEF2A (Ser408) Antibody detects transfected levels of MEF2A only when phosphorylated at Ser408. The antibody has also been shown to detect phospho-MEF2A (Ser408) in granule neurons (see application reference).
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser408 of human MEF2A. Antibodies are purified by protein A and peptide affinity chromatography.
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 (1). 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 (2,3). Phosphorylation of MEF2A at Thr312 and Thr319 within the transcription activation domain by p38 MAP kinase enhances MEF2A-MEF2D heterodimer-dependent gene expression (4). 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 (5).
