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
spaNSurface 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. (336 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
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
spaI
Secretory 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).
  
  
 0.999
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.
   
  
 0.998
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.
  
  
 0.998
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).
  
  
 0.996
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.
  
  
 0.993
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.

prgK
Pathogenicity 1 island effector protein; Similar to several proteins essential for protein secretion by a type III system: Salmonella typhimurium protein precursor PrgK required for invasion of epithelial cells SW:PRGK_SALTY (P41786) (252 aa) fasta scores: E(): 0, 99.6% id in 252 aa and Shigella flexneri lipoprotein MxiJ secretion protein SW:MXIJ_SHIFL (Q06081) (241 aa) fasta scores: E(): 0, 46.1% id in 243 aa. Contains a possible N-terminal signal sequence.
