Protein Classification

MEF2 family transcription factor( domain architecture ID 13416711)

MEF2 family transcription factor is a MADS (MCM1, Agamous, Deficiens, and SRF)-box transcription factor, similar to human myocyte-specific enhancer factor 2C, a transcription activator which binds specifically to the MEF2 element present in the regulatory regions of many muscle-specific genes

 2-78 1.80e-38

MEF2 (myocyte enhancer factor 2)-like/Type II subfamily of MADS ( MCM1, Agamous, Deficiens, and SRF (serum response factor) box family of eukaryotic transcriptional regulators. Binds DNA and exists as hetero and homo-dimers. Differs from SRF-like/Type I subgroup mainly in position of the alpha helix responsible for the dimerization interface. Important in homeotic regulation in plants and in immediate-early development in animals. Also found in fungi.
