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:
SQD1UDP-sulfoquinovose synthase, chloroplastic; Involved in the biosynthesis of sulfolipids found in thylakoid membranes. Converts UDP-glucose and sulfite to the sulfolipid head group precursor UDP-sulfoquinovose; Belongs to the NAD(P)-dependent epimerase/dehydratase family. (477 aa)
PER13Peroxidase 13; 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. (319 aa)
CAX1Vacuolar cation/proton exchanger 1; Vacuolar cation/proton exchanger (CAX). Translocates Ca(2+) and other metal ions into vacuoles using the proton gradient formed by H(+)-ATPase and H(+)-pyrophosphatase. Involved in ion homeostasis in association with CAX3. May play a role in cold-acclimation response. Belongs to the Ca(2+):cation antiporter (CaCA) (TC 2.A.19) family. Cation/proton exchanger (CAX) subfamily. (463 aa)
SPX3SPX domain-containing protein 3; Plays a positive role in plant adaptation to phosphate starvation and exerts negative feedback regulation of SPX1. (245 aa)
SQD2Sulfoquinovosyl transferase SQD2; Catalyzes the transfer of the sulfoquinovose moiety from UDP- sulfoquinovose to diacylglycerol during sulfolipid biosynthesis. Sulfolipid contributes to maintaining a negatively charged lipid-water interface, a requirement for proper function of photosynthetic membranes. Sulfolipid may also function as a substitute of anionic phospholipids under phosphate-limited growth conditions. (510 aa)
SPX1SPX domain-containing protein 1; Plays a positive role in plant adaptation to phosphate starvation. Inhibits PHR1 DNA-binding activity in a Pi-dependent manner. (256 aa)
UBC24Probable ubiquitin-conjugating enzyme E2 24; Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (By similarity). Mediates PHO1 degradation through multivesicular body-mediated vacuolar proteolysis in response to inorganic phosphate (Pi) availability. Negatively regulates the protein abundance of PHF1 and PHT1s under Pi- sufficient conditions by facilitating the degradation of PHT1 proteins at the endomembrane. (907 aa)
CAX3Vacuolar cation/proton exchanger 3; Vacuolar cation/proton exchanger (CAX). Translocates Ca(2+) and other metal ions into vacuoles using the proton gradient formed by H(+)-ATPase and H(+)-pyrophosphatase (By similarity). Involved in ion homeostasis in association with CAX1; Belongs to the Ca(2+):cation antiporter (CaCA) (TC 2.A.19) family. Cation/proton exchanger (CAX) subfamily. (459 aa)
SPX2SPX domain-containing protein 2; May inhibit PHR1 DNA-binding activity in a Pi-dependent manner. (287 aa)
