myocyte enhancer factor 2, isoform C [Drosophila melanogaster]

Protein Classification

myocyte-specific enhancer factor 2( domain architecture ID 10083624)

myocyte-specific enhancer factor 2 (MEF2) is a MADS (MCM1, AGAMOUS, DEFICIENS, and SRF, serum response factor) domain transcription factor, such as human MEF2C, a transcription activator which binds specifically to the MEF2 element present in the regulatory regions of many muscle-specific genes

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.

Holliday junction regulator protein family C-terminal repeat; Although this family is conserved in the Holliday junction regulator, HJURP, proteins in higher eukaryotes, alongside an Scm3, pfam10384, family, its exact function is not known. The C-terminal region of Scm3 proteins has been evolving rapidly, and this short repeat at the C-terminal end can be present in up to two copies in the higher eukaryotes.
