Transcription factor involved in the developmental regulation of the endothelium and in the accumulation of proanthocyanidins (PAs) or condensed tannins which give the seed its brown pigmentation after oxidation. Necessary for the normal activation of the BANYULS promoter in the endothelium body. Arabidopsis thaliana (taxid: 3702)
>sp|Q9FVC1|SVP_ARATH MADS-box protein SVP OS=Arabidopsis thaliana GN=SVP PE=1 SV=1
Transcription repressor that inhibit floral transition in the autonomous flowering pathway, independent of photoperiod and temperature. Acts in a dosage-dependent manner. Together with AGL24 and AP1, controls the identity of the floral meristem and regulates expression of class B, C and E genes.
Probable transcription factor involved in the development of floral organs. Required for normal development of lodicules and stamens (whorls 2 and 3). May function as an heterodimer with MADS4.
Oryza sativa subsp. japonica (taxid: 39947)
>sp|Q03378|GLOB_ANTMA Floral homeotic protein GLOBOSA OS=Antirrhinum majus GN=GLO PE=1 SV=1
Probable transcription factor. Functions with SEPALLATA1/AGL2 and SEPALLATA3/AGL9 to ensure proper development of petals, stamens and carpels and to prevent the indeterminate growth of the flower meristem. Forms an heterodimer via the K-box domain with AG, that could be involved in genes regulation during floral meristem development.
Transcriptional activator which binds specifically to the MEF2 element, 5'-YTA[AT](4)TAR-3', found in numerous muscle-specific genes. Activates transcription via this element. May be involved in muscle-specific and/or growth factor-related transcription.

>PF00319 SRF-TF: SRF-type transcription factor (DNA-binding and dimerisation domain); InterPro: IPR002100 Human serum response factor (SRF) is a ubiquitous nuclear protein important for cell proliferation and differentiation
SRF function is essential for transcriptional regulation of numerous growth-factor-inducible genes, such as c-fos oncogene and muscle-specific actin genes. A core domain of around 90 amino acids is sufficient for the activities of DNA-binding, dimerisation and interaction with accessory factors. Within the core is a DNA-binding region, designated the MADS box [], that is highly similar to many eukaryotic regulatory proteins: among these are MCM1, the regulator of cell type-specific genes in fission yeast; DSRF, a Drosophila trachea development factor; the MEF2 family of myocyte-specific enhancer factors; and the Agamous and Deficiens families of plant homeotic proteins. In SRF, the MADS box has been shown to be involved in DNA-binding and dimerisation []. Proteins belonging to the MADS family function as dimers, the primary DNA-binding element of which is an anti-parallel coiled coil of two amphipathic alpha-helices, one from each subunit. The DNA wraps around the coiled coil allowing the basic N-termini of the helices to fit into the DNA major groove. The chain extending from the helix N-termini reaches over the DNA backbone and penetrates into the minor groove. A 4-stranded, anti-parallel beta-sheet packs against the coiled-coil face opposite the DNA and is the central element of the dimerisation interface. The MADS-box domain is commonly found associated with K-box region see IPR002487 from INTERPRO ; GO: 0003677 DNA binding, 0046983 protein dimerization activity; PDB: 1MNM_B 1N6J_A 1TQE_S 3MU6_D 3P57_I 1EGW_A 1C7U_B 3KOV_A 1HBX_A 1K6O_C ....
