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

yfkEPutative H+/Ca2+ antiporter; Ca(+)/H(+) antiporter that extrudes calcium in exchange for external protons. Does not transport sodium or potassium. Belongs to the Ca(2+):cation antiporter (CaCA) (TC 2.A.19) family. Cation/proton exchanger (CAX) subfamily. (351 aa)    
Predicted Functional Partners:
yfkD
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

yloB
P-type calcium transport ATPase; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium.

mrpD
Proton transporter component of Na+/H+ antiporter; Mrp complex is a Na(+)/H(+) antiporter that is considered to be the major Na(+) excretion system in B.subtilis. Has a major role in Na(+) resistance and a minor role in Na(+)- and K(+)-dependent pH homeostasis as compared to TetB. MrpA may be the actual Na(+)/H(+) antiporter, although the six other Mrp proteins are all required for Na(+)/H(+) antiport activity and Na(+) resistance. MrpA is required for initiation of sporulation when external Na(+) concentration increases. Also transports Li(+) but not K(+), Ca(2+) or Mg(2+). Belongs to [...]
