Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

FAMATranscription factor FAMA; Transcription activator. Together with MYB88 and MYB124, ensures that stomata contain just two guard cells (GCs) by enforcing a single symmetric precursor cell division before stomatal maturity. Together with SPCH and MUTE, regulates the stomata formation. Required to promote differentiation and morphogenesis of stomatal guard cells and to halt proliferative divisions in their immediate precursors. Mediates the formation of stomata. Prevents histone H3K27me3 marks and derepresses stem cell gene expression. (414 aa)
BASLProtein BREAKING OF ASYMMETRY IN THE STOMATAL LINEAGE; Regulates asymmetric cell division (ACD), especially in stomatal-lineage cells, probably by modulating accumulation and subcellular polarization of POLAR and SPCH. Mediates an attenuation of MAPK signaling upon polarization of POLAR and ASK7/BIN2 in stomatal lineage ground cells (SLGCs) undergoing ACD, and relieves BIN2 inhibition of SPCH in the nucleus. When phosphorylated, functions as a scaffold and recruits the MAPKKK YODA, MPK3 and MPK6 to spatially reorganize the MAPK signaling pathway at the cortex of cells undergoing ACD. C [...] (262 aa)
ERL2LRR receptor-like serine/threonine-protein kinase ERL2; Receptor kinase that regulates inflorescence architecture and organ shape as well as stomatal patterning, including density and clustering, together with ERL1 and ER. (967 aa)
SPCHTranscription factor SPEECHLESS; Transcription factor acting as an integration node for stomata and brassinosteroid (BR) signaling pathways to control stomatal initiation and development. Activates transcription when in the presence of SCRM/ICE1. Functions as a dimer with SCRM or SCRM2 during stomatal initiation. Required for the initiation, the spacing and the formation of stomata, by promoting the first asymmetric cell divisions. Together with FMA and MUTE, modulates the stomata formation. Involved in the regulation of growth reduction under osmotic stress (e.g. mannitol), associated [...] (364 aa)
EPF2Protein EPIDERMAL PATTERNING FACTOR 2; Controls stomatal patterning. Regulates the number of cells that enter, and remain in, the stomatal lineage by inhibiting protodermal cells from adopting the meristemoid mother cell (MMC) fate in a non-cell-autonomous manner. Mediates stomatal development inhibition. MEPF2: mobile signal controlling stomatal development in a non-cell-autonomous manner. Uses ERECTA as major receptor. Inactivated by cleavage by CRSP (AC Q9LNU1). May act by competing with somatogen (AC Q9SV72) for the same receptor, TMM (AC Q9SSD1). (120 aa)

RBR1Retinoblastoma-related protein 1; Key regulator of entry into cell division. Acts as a transcription repressor of E2F target genes, whose activity is required for progress from the G1 to the S phase of the cell cycle. Hyperphosphorylation by CDKA-1 prevents the binding to E2F transcription factors, allowing G1 to S phase transition to operate. Forms a stable complex with E2FA that functions in maintaining cell proliferation through repression of cell differentiation. Plays a central role in the mechanism controlling meristem cell differentiation, cell fate establishment and cell fate m [...] (1013 aa)
