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:
SPX2SPX domain-containing protein 2; May inhibit PHR1 DNA-binding activity in a Pi-dependent manner. (287 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)
PHR1Protein PHOSPHATE STARVATION RESPONSE 1; Transcription factor involved in phosphate starvation signaling. Binds as a dimer to P1BS, an imperfect palindromic sequence 5'-GNATATNC-3', to promote the expression of inorganic phosphate (Pi) starvation- responsive genes. SPX1 is a competitive inhibitor of this DNA-binding. PHR1 binding to its targets is low Pi-dependent. Regulates the expression of miR399. Regulates the expression of IPS1 (At3g09922), a non-coding RNA that mimics the target of miR399 to block the cleavage of PHO2 under Pi-deficient conditions. Regulates lipid remodeling and [...] (409 aa)
