Antigen/Purification: ExpandCollapse

The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho Ser222 of the human MEF2C protein.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.

Biological Significance: ExpandCollapse

MEF2C, also known as MADS box transcription enhancer factor 2, polypeptide C, is one of 4 MEF2 (myocyte enhancer factor 2) transcription factors that encode proteins for development of skeletal muscle and brain proliferation and differentiation (McDermott et al, 1993), along with regulating stress-response during cardiac hypertrophy in mammals (Wu et al, 2015). Phosphorylation of MEF2C at serine 59 has been shown to be negatively regulated by integrin-linked kinase (ILK) (Dong et al, 2015). Recently, high MEF2C expression has been associated with a subset of acute myeloid leukemia (AML) patients with adverse-risk disease features and poor outcomes (Laszlo et al, 2015). Phosphorylation of MEF2C at serine 222 may play a key role in MEF2C signaling.

MEF2C Ser222 Antibody
Western blot of OCIAML2 lysate showing specific immunolabeling of the ~51 kDa MEF2C phosphorylated at Ser222 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase ((λ-Ptase, 1200 units for 30 minutes).
