Probable mobile flower-promoting signal (florigen) that moves from the leaf to the shoot apical meristem (SAM) and induces flowering. Promotes the transition from vegetative growth to flowering downstream of HD1 and EHD1 under short day (SD) conditions. Acts upstream of MADS14 and MADS15. Oryza sativa subsp. japonica (taxid: 39947)
>sp|Q9SXZ2|FT_ARATH Protein FLOWERING LOCUS T OS=Arabidopsis thaliana GN=FT PE=1 SV=2
Probable component of the mobile flower-promoting signal (floral stimulus or florigen). Promotes the transition from vegetative growth to flowering. Required for 'SEPALLATA3' (SEP3) and 'FRUITFULL' (FUL) accumulation in mature rosette leaves. Seems to acts in parallel with 'LEAFY' to induce flowering by regulating 'APETALA1'. May play a role in both the autonomous and the long-day flowering pathways.

Probable mobile flower-promoting signal (florigen) that moves from the leaf to the shoot apical meristem (SAM) and induces flowering. Promotes the transition from vegetative growth to flowering under long day (LD) conditions. Acts upstream of MADS14 and MADS15.

Controls inflorescence meristem identity and is required for maintenance of a indeterminate inflorescence. Prevents the expression of 'APETALA1' and 'LEAFY'. Also plays a role in the regulation of the time of flowering in the long-day flowering pathway. May form complexes with phosphorylated ligands by interfering with kinases and their effectors.

PhosphatidylEthanolamine-Binding Proteins (PEBPs) are represented in all three major phylogenetic divisions (eukaryotes, bacteria, archaea). The members in this subgroup are present in eukaryotes. Members here include those in plants such as Arabidopsis thaliana FLOWERING LOCUS (FT) and TERMINAL FLOWER1 (FT1) which function as a promoter and a repressor of the floral transitions, respectively as well as the mammalian Raf kinase inhibitory protein (RKIP) which inhibits MAP kinase (Raf-MEK-ERK), G protein-coupled receptor (GPCR) kinase and NFkappaB signaling cascades. Although their overall structures are similar, the members of the PEBP family have very different substrates and oligomerization states (monomer/dimer/tetramer). Length = 154

>PF01161 PBP: Phosphatidylethanolamine-binding protein; InterPro: IPR008914 The PEBP (PhosphatidylEthanolamine-Binding Protein) family is a highly conserved group of proteins that have been identified in numerous tissues in a wide variety of organisms, including bacteria, yeast, nematodes, plants, drosophila and mammals
The various functions described for members of this family include lipid binding, neuronal development [], serine protease inhibition [], the control of the morphological switch between shoot growth and flower structures [], and the regulation of several signalling pathways such as the MAP kinase pathway [], and the NF-kappaB pathway []. The control of the latter two pathways involves the PEBP protein RKIP, which interacts with MEK and Raf-1 to inhibit the MAP kinase pathway, and with TAK1, NIK, IKKalpha and IKKbeta to inhibit the NF-kappaB pathway. Other PEBP-like proteins that show strong structural homology to PEBP include Escherichia coli YBHB and YBCL, the Rattus norvegicus (Rat) neuropeptide HCNP, and Antirrhinum majus (Garden snapdragon) protein centroradialis (CEN). Structures have been determined for several members of the PEBP-like family, all of which show extensive fold conservation. The structure consists of a large central beta-sheet flanked by a smaller beta-sheet on one side, and an alpha helix on the other. Sequence alignments show two conserved central regions, CR1 and CR2, that form a consensus signature for the PEBP family. These two regions form part of the ligand-binding site, which can accommodate various anionic groups. The N- and C-terminal regions are the least conserved, and may be involved in interactions with different protein partners. The N-terminal residues 2-12 form the natural cleavage peptide HCNP involved in neuronal development. The C-terminal region is deleted in plant and bacterial PEBP homologues, and may help control accessibility to the active site. ; PDB: 1BD9_A 1BEH_A 2QYQ_A 2L7W_A 3AXY_A 2IQX_C 2IQY_A 1KN3_A 1FUX_A 1B7A_A ....

PhosphatidylEthanolamine-Binding Proteins (PEBPs) are represented in all three major phylogenetic divisions (eukaryotes, bacteria, archaea). A number of biological roles for members of the PEBP family include serine protease inhibition, membrane biogenesis, regulation of flowering plant stem architecture, and Raf-1 kinase inhibition. Although their overall structures are similar, the members of the PEBP family bind very different substrates including phospholipids, opioids, and hydrophobic odorant molecules as well as having different oligomerization states (monomer/dimer/tetramer).
PhosphatidylEthanolamine-Binding Proteins (PEBPs) are represented in all three major phylogenetic divisions (eukaryotes, bacteria, archaea). The members in this subgroup are present in bacterial and archaea. Members here include Escherichia coli YBHB and YBCL which are thought to regulate protein phosphorylation as well as Sulfolobus solfataricus SsCEI which inhibits serine proteases alpha-chymotrypsin and elastase. Although their overall structures are similar, the members of the PEBP family have very different substrates and oligomerization states (monomer/dimer/tetramer). In a few of the bacterial members present here the dimerization interface is proposed to form the ligand binding site, unlike in other PEBP members.
