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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
PRF4Profilin-4; Binds to actin monomers and regulates the organization of the actin cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. At low concentrations, associates with the poly-proline motif of formins to enhance actin filament elongation rate. Acts redundantly with PRF5 to regulate apical actin polymerization at the tip of pollen tube and control polarized pollen tube growth. Functions probably by favoring formin-mediated actin polymerization at pollen tube tips. (134 aa)
PRF5Profilin-5; Binds to actin monomers and regulates the organization of the actin cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. At low concentrations, associates with the poly-proline motif of formins to enhance actin filament elongation rate. Acts redundantly with PRF4 to regulate apical actin polymerization at the tip of pollen tube and control polarized pollen tube growth. Functions probably by favoring formin-mediated actin polymerization at pollen tube tips. (134 aa)
PRF2Profilin-2; Binds to actin monomers and regulates the organization of the actin cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. At low concentrations, associates with the poly-proline motif of formins to enhance actin filament elongation rate. Binds G- actin and poly-L-proline with low affinity in vitro. Binds ACT1, ACT7 and ACT11 and inhibits actin polymerization. May be involved in the cross-talk between vesicular trafficking and the actin cytoskeleton. At high concentrations, profilin prevents the pol [...] (131 aa)
PRF1Profilin-1; Binds to actin monomers and regulates the organization of the actin cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. At low concentrations, associates with the poly-proline motif of formins to enhance actin filament elongation rate. Binds ACT1, ACT7 and ACT11 and inhibits actin polymerization. Coordinates the stochastic dynamic properties of actin filaments by modulating formin- mediated actin nucleation and assembly during axial cell expansion. Binds G-actin and poly-L-proline in vitro. Inhib [...] (131 aa)
ADF7Actin-depolymerizing factor 7; Actin-depolymerizing protein. Severs actin filaments (F- actin) and binds to actin monomers. Binds monomeric actin (G-actin) with a marked preference for the ADP-loaded form and inhibits the rate of nucleotide exchange on G-actin. Required for pollen tube growth. Promotes turnover of longitudinal actin cables by severing actin filaments in pollen tubes. (137 aa)
PER12Peroxidase 12; Removal of H(2)O(2), oxidation of toxic reductants, biosynthesis and degradation of lignin, suberization, auxin catabolism, response to environmental stresses such as wounding, pathogen attack and oxidative stress. These functions might be dependent on each isozyme/isoform in each plant tissue; Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily. (358 aa)
PRF3Profilin-3; Binds to actin monomers and regulates the organization of the actin cytoskeleton. Can increase the critical concentration (Cc) of actin assembly in vitro. Acts as downstream effector of the hydrogen sulfide signaling to regulate the assembly and depolymerization of F-actin. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations (Probable). Binding to the poly-proline motif of formin induces oligomerization of PRF3. PRF3 oligomers inhibit formin-mediated actin assembly to modulate plant immunity triggered by pathog [...] (168 aa)
PCAP2Plasma membrane-associated cation-binding protein 2; May be involved in intracellular signaling through interaction with PtdInsPs and calmodulin (CaM); may keep PtdInsPs attached to the plasma membrane until Ca(2+)-CaM reaches a competitive concentration subsequent to an increase triggered by a stimulus, thus leading to PtdInsPs release and subsequent activation of InsPs- dependent signaling cascade (Probable). Binds to microtubules and inhibits tubulin polymerization. Regulates directional cell growth and cortical microtubule organization by destabilizing microtubules (e.g. in cotyled [...] (168 aa)
