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

Score
spaISecretory apparatus ATP synthase (associated with virulence); Necessary for efficient entry of S.typhimurium into cultured epithelial cells. Probable catalytic subunit of a protein translocase. May energize the protein export apparatus encoded in the inv locus which is required for the surface presentation of determinants needed for the entry of salmonella species into mammalian cells (By similarity). (431 aa)    
Predicted Functional Partners:
spaP
Secretory protein (associated with virulence); Involved in a secretory pathway responsible for the surface presentation of determinants needed for the entry of Salmonella species into mammalian cells; Belongs to the FliP/MopC/SpaP family.
 
  
 0.999
spaN
Surface presentation of antigens protein (associated with type III secretion and virulence); Highly similar to Salmonella typhimurium surface presentation of antigens protein SpaN SW:SPAN_SALTY (P40613) (336 aa) fasta scores: E(): 0, 98.2% id in 336 aa.
  
  
 0.999
spaM
Secretory protein (associated with virulence); Similar to Salmonella typhimurium surface presentation of antigens protein spaM SW:SPAM_SALTY (P40612) (147 aa) fasta scores: E(): 0, 99.3% id in 147 aa. Contains possible coiled-coils between residues 75..110.
  
  
 0.999
invA
Possible secretory protein (associated with virulence); Involved in the invasion of the cells of the intestinal epithelium. Could be involved in the translocation of the InvE protein (By similarity); Belongs to the FHIPEP (flagella/HR/invasion proteins export pore) family.
 
  
 0.999
invG
Secretory protein (associated with virulence); Highly similar to Salmonella typhimurium InvG protein precursor SW:INVG_SALTY (P35672) (562 aa) fasta scores: E(): 0, 99.1% id in 562 aa and to Shigella flexneri outer membrane protein MxiD SW:MXID_SHIFL (Q04641) (566 aa) fasta scores: E(): 0, 50.9% id in 489 aa. Contains a possible N-terminal signal sequence.
 
 
 0.999
spaS
Secretory protein (associated with virulence); Similar to Salmonella typhimurium surface presentation of antigens protein SpaS SW:SPAS_SALTY (P40702) (356 aa) fasta scores: E(): 0, 99.4% id in 356 aa. Contains possible membrane spanning hydrophobic domains.
 
 
 0.998
spak
Secretory protein (associated with virulence); Involved in a secretory pathway responsible for the surface presentation of determinants needed for the entry of Salmonella species into mammalian cells.
  
  
 0.998
prgH
Pathogenicity 1 island effector protein; Similar to Salmonella typhimurium protein PrgH required for invasion of epithelial cells SW:PRGH_SALTY (P41783) (392 aa) fasta scores: E(): 0, 99.2% id in 392 aa. Contains possible membrane spanning hydrophobic domains.
   
  
 0.997
invE
Cell invasion protein; Involved in the triggering of intracellular events that lead to microbial internalization. These events include increase in calcium level, redistribution of actin microfilaments, and changes in the normal structure of the microvilli. Encoded within the type III secretion system (SPI-1 TTSS), it is essential for the translocation of protein effectors into host cells. Forms a complex with SipB and SipC in the presence of their chaperone SicA (By similarity).
  
  
 0.995
spaT
Unknown function; Type III secretion-associated chaperone required for SipB and SipC stabilization. Prevents premature association of SipB with SipC, which may lead to their targeting for degradation. Along with InvF, required for transcription activation of sigDE (sopB pipC), sicAsipBCDA, and sopE (By similarity).
