Protein Classification

MADS-box domain-containing protein( domain architecture ID 10083661)

MADS-box domain-containing protein with a K-box coiled-coil region; the MADS-box domain (MCM1, AGAMOUS, DEFICIENS, and SRF, serum response factor) is a conserved DNA-binding/dimerization region present in a variety of transcription factors from three eukaryotic kingdoms, plants, animals, and fungi

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.

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