Anti-MEF2C (Myocyte-specific Enhancer Factor 2C)

MEF2C is a transcriptional activator that is a member of the MEF2 subfamily, MADS (MCM1, Agamous, Deficiens, Serum response factor) gene family of proteins. Although its predicted MW is 51kD, it runs anomalously at 57kD in SDS-PAGE. It is expressed in B cells, plus postmitotic neurons and skeletal muscle cells that are undergoing differentiation. Human MEF2C is 473aa in length. It contains a MADS box for dimerization aa3-57, a DNA binding domain aa58-86, a beta-domain that enhances transcription aa271-278, a gamma-domain that, when phosphorylated, promotes transcriptional repression aa390-399, and seven acetylation sites plus multiple Ser/Thr phosphorylation sites. Sumoylation occurs on Lys391, and proteolytic cleavage of MEF2C occurs in neurons between aa432-433. Multiple splice forms exist. Either individually or in combination, there may be a deletion of aa271-278, 368-399 or 87-134, a 46aa substitution for aa107-134 and 87-134, and an alternative start site 35aa upstream of the standard site. Over aa135-239, human MEF2C shares 96% aa identity with mouse MEF2C. Applications: Suitable for use in Western Blot. Other applications not tested.
