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. Arabidopsis thaliana (taxid: 3702)

>sp|O82794|AGL24_ARATH MADS-box protein AGL24 OS=Arabidopsis thaliana GN=AGL24 PE=1 SV=1
Transcription activator that mediates floral transition in response to vernalization. Promotes inflorescence fate in apical meristems. Acts in a dosage-dependent manner. Probably involved in the transduction of RLK-mediated signaling (e.g. IMK3 pathway). Together with AP1 and SVP, controls the identity of the floral meristem and regulates expression of class B, C and E genes. When associated with SOC1, mediates effect of gibberellins on flowering under short-day conditions, and regulates the expression of LEAFY (LFY), which links floral induction and floral development. Confers inflorescence characteristics to floral primordia and early flowering.
Transcription factor involved in the negative regulation of flowering, probably through the photoperiodic pathway. Acts as both an activator and a repressor of transcription. Binds DNA in a sequence-specific manner in large CArG motif 5'-CC (A/T)8 GG-3'. Participates probably in the regulation of programs active during the early stages of embryo development. Prevents premature perianth senescence and abscission, fruits development and seed desiccation. Stimulates the expression of at least DTA4, LEC2, FUS3, ABI3, AT4G38680/CSP2 and GRP2B/CSP4. Can enhance somatic embryo development in vitro.

>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 ....
