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

sapMAcid phosphatase (acid phosphomonoesterase) (phosphomonoesterase) (glycerophosphatase); Virulence factor that plays an important role in blocking phagosome-lysosome fusion and thus participates in the intracellular survival of the pathogen. Acts as a phosphatase that dephosphorylates phosphatidylinositol 3-phosphate (PI3P), a membrane trafficking regulatory lipid essential for phagosomal acquisition of lysosomal constituents. Therefore, SapM eliminates PI3P from the phagosomal membrane by catalyzing its hydrolysis, and thus contributes to inhibition of phagosome maturation. Also interf [...] (299 aa)    
Predicted Functional Partners:
plcA
Membrane-associated phospholipase C 1 PlcA (MTP40 antigen); Hydrolyzes sphingomyelin in addition to phosphatidylcholine. Probable virulence factor implicated in the pathogenesis of M.tuberculosis at the level of intracellular survival, by the alteration of cell signaling events or by direct cytotoxicity; Belongs to the bacterial phospholipase C family.

plcD
Rv1755c, (MT1799, MTCY28.21c), len: 280 aa. Probable plcD, phospholipase C 4 (fragment) (see citations below),highly similar to C-terminus of other phospholipases e.g. CQ50771|Rv2351c|PLCA|MTP40|MT2416|MTCY98.20c phospholipase C 1 from Mycobacterium tuberculosis (512 aa), FASTA score: (71.1% identity in 284 aa overlap); etc. Note that this ORF has been interrupted by insertion of IS6110 element. Belongs to the bacterial phospholipase C family.

ptpA
Phosphotyrosine protein phosphatase PtpA (protein-tyrosine-phosphatase) (PTPase) (LMW phosphatase); Mediates host-pathogen interaction and interferes with vesicular trafficking in the infected macrophage. Inhibits host phagolysosomal fusion in M.tuberculosis-infected macrophages to promote bacteria survival. Dephosphorylates host VPS33B protein, which induces a block of the host phagosome maturation within macrophage cells. Acts on tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates; Belongs to the low molecular weight phosphotyrosine prot [...]
