STRINGSTRING
STRING protein interaction network
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

phoURegulatory gene for high affinity phosphate uptake; Part of the phosphate (Pho) regulon, which plays a key role in phosphate homeostasis. PhoU is essential for the repression of the Pho regulon at high phosphate conditions. (241 aa)    
Predicted Functional Partners:
pstB
High-affinity phosphate transporter; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Phosphate importer (TC 3.A.1.7) family.
  
 0.999
pstA
ABC superfamily (membrane); similar to E. coli high-affinity phosphate-specific transport system (AAC76749.1); Blastp hit to AAC76749.1 (296 aa), 95% identity in aa 1 - 296.
  
 0.999
pstC
High-affinity phosphate transporter; Part of the binding-protein-dependent transport system for phosphate; probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
 
  
 0.987
pstS
High-affinity phosphate transporter; Part of the ABC transporter complex PstSACB involved in phosphate import; Belongs to the PstS family.
 
  
 0.979
phoR
Sensory kinase in two-component regulatory system with PhoB, regulates pho regulon; Similar to E. coli positive and negative sensor protein for pho regulon (AAC73503.1); Blastp hit to AAC73503.1 (431 aa), 90% identity in aa 1 - 431.
