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

kdpDProbable sensor protein KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of KdpE in response to environmental signals such as low levels of potassium ion, osmotic imbalance, acid and nutrient stresses. In turn, KdpE binds to the upstream promoter regions of target genes to positively regulate their expression. (860 aa)    
Predicted Functional Partners:
kdpE
Probable transcriptional regulatory protein KdpE; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Upon phosphorylation by KdpD, functions as a transcription regulator by direct binding to promoter regions of target genes to positively regulate their expression.

kdpC
Potassium-transporting ATPase KdpC subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.
 
  
 0.994
kdpB
Potassium-transporting ATPase ATP-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit is responsible for energy coupling to the transport system. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IA subfamily.
 
  
 0.992
kdpA
Potassium-transporting ATPase potassium-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds and transports the potassium across the cytoplasmic membrane.

lprF
Probable conserved lipoprotein LprF; Might be involved in transporting short diacylated glycolipids to the cell outer membrane (By similarity). Overexpression induces expression of sensor protein kdpD gene at low K(+) concentrations (0 and 250 uM, tested in M.smegatis). Belongs to the LppX/LprAFG lipoprotein family.
   
  
 0.904
lprJ
Probable lipoprotein LprJ; Overexpression induces expression of sensor protein kdpD gene at low K(+) concentrations (0 and 250 uM, tested in M.smegatis).

trcR
Rv1033c, (MTCY10G2.16), len: 257 aa. TrcR,two-component regulatory protein (see citations below),similar to Q50825 two component response regulator from Mycobacterium tuberculosis (234 aa), FASTA scores: opt: 628, E(): 0, (46.0% identity in 226 aa overlap). Note that in vitro autophosphorylation of TrcS requires the presence of Mn2+or Ca2+as a divalent cation cofactor and subsequent transphosphorylation of TrcR is evident in the presence of TrcS-phosphate and Ca2+.

kdpF
Rv1028A, len: 30 aa. Probable kdpF, membrane protein, showing similarity with P36937|KDPF_ECOLI|B0698.1 protein KDPF from Escherichia coli strain K12 (see citation below) (27% identity); and KdpF protein from Streptomyces coelicolor (51% identity).

mtrA
Two component sensory transduction transcriptional regulatory protein MtrA; Member of the two-component regulatory system MtrA/MtrB. Binds direct repeat motifs of sequence 5'-GTCACAGCG-3', phosphorylation confers higher affinity. Overexpression decreases bacteria viability upon infection of human THP-1 macrophage cell line, due at least in part to impaired blockage of phagosome-lysosome fusion (upon infection bacteria usually remain in phagosomes). Infecting C57BL/6 mice with an overexpressing strain leads to an attentuated infection in both spleen and lungs. The level of dnaA mRNA inc [...]

prrA
Two component response transcriptional regulatory protein PrrA; Member of the two-component regulatory system PrrB/PrrA that is involved specifically in early intracellular multiplication of Mycobacterium and is essential for its viability. Upon phosphorylation by PrrB, functions as a transcription regulator by direct binding to promoter regions of target genes to positively regulate their expression. Autoregulates its own expression.
