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

GJD4Gap junction delta-4 protein; One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell; Belongs to the connexin family. Delta-type subfamily. (370 aa)    
Predicted Functional Partners:
FXYD4
FXYD domain containing ion transport regulator 4.
   
  
 0.961
GJE1
Putative gap junction epsilon-1 protein; Mediates calcium-independent ATP release, suggesting activity as a hemichannel. Does not form functional gap junctions. Belongs to the connexin family. Beta-type (group I) subfamily.
     
0.582
ZBBX
Zinc finger B-box domain containing.
      
 0.524
TBC1D22B
TBC1 domain family member 22B; May act as a GTPase-activating protein for Rab family protein(s).
      
 0.511
GJA8
Gap junction alpha-8 protein; Structural component of eye lens gap junctions. Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells. They are formed by the docking of two hexameric hemichannels, one from each cell membrane (By similarity). Small molecules and ions diffuse from one cell to a neighboring cell via the central pore.

NRSN2
Neurensin-2; May play a role in maintenance and/or transport of vesicles; Belongs to the VMP family.
      
 0.480
CALHM1
Calcium homeostasis modulator protein 1; Pore-forming subunit of a voltage-gated ion channel required for sensory perception of sweet, bitter and umami tastes (By similarity). Specifically present in type II taste bud cells, where it plays a central role in sweet, bitter and umami taste perception by inducing ATP release from the cell, ATP acting as a neurotransmitter to activate afferent neural gustatory pathways (By similarity). Together with CALHM3, forms a fast-activating voltage-gated ATP-release channel in type II taste bud cells (TBCs) (By similarity). Acts both as a voltage-gat [...]

GJD3
Gap junction delta-3 protein; One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell; Belongs to the connexin family. Delta-type subfamily.

PLCD4
1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase delta-4; Hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP2) to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). DAG mediates the activation of protein kinase C (PKC), while IP3 releases Ca(2+) from intracellular stores. Required for acrosome reaction in sperm during fertilization, probably by acting as an important enzyme for intracellular Ca(2+) mobilization in the zona pellucida-induced acrosome reaction. May play a role in cell growth. Modulates the liver regeneration [...]
