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

OTOP2Proton channel OTOP2; Proton-selective channel that specifically transports protons into cells. Proton-selective channel activity is probably required in cell types that use changes in intracellular pH for cell signaling or to regulate biochemical or developmental processes. Belongs to the otopetrin family. (562 aa)    
Predicted Functional Partners:
BEST4
Bestrophin-4; Forms calcium-sensitive chloride channels. Permeable to bicarbonate.

OC90
Otoconin-90; Major protein of the otoconia, a calcium carbonate structure in the saccule and utricle of the ear. Together with OTOL1, acts as a scaffold for otoconia biomineralization: sequesters calcium and forms interconnecting fibrils between otoconia that are incorporated into the calcium crystal structure. Together with OTOL1, modulates calcite crystal morphology and growth kinetics. It is unlikely that this protein has phospholipase A2 activity.
      
 0.599
GUCA2B
Guanylate cyclase C-activating peptide 2; Endogenous activator of intestinal guanylate cyclase. It stimulates this enzyme through the same receptor binding region as the heat-stable enterotoxins. May be a potent physiological regulator of intestinal fluid and electrolyte transport. May be an autocrine/paracrine regulator of intestinal salt and water transport.
   
  
 0.596
ATP2B2
Plasma membrane calcium-transporting ATPase 2; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell.
      
 0.538
TMIGD1
Transmembrane and immunoglobulin domain-containing protein 1; May control cell-cell adhesion, cell migration and proliferation, cell morphology, and protects renal epithelial cells from oxidative cell injury to promote cell survival.
   
  
 0.494
FATE1
Fetal and adult testis-expressed transcript protein; Involved in the regulation of endoplasmic reticulum (ER)- mitochondria coupling. Negatively regulates the ER-mitochondria distance and Ca(2+) transfer from ER to mitochondria possibly implicating it in the regulation of apoptosis. May collaborate with RNF183 to restrain BIK protein levels thus regulating apoptotic signaling.
   
   0.489
TMEM82
Transmembrane protein 82.
   
  
 0.488
TMEM128
Transmembrane protein 128.
 
    
 0.452
ATP2B4
Plasma membrane calcium-transporting ATPase 4; Calcium/calmodulin-regulated and magnesium-dependent enzyme that catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell. By regulating sperm cell calcium homeostasis, may play a role in sperm motility (By similarity). Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily.
      
 0.440
MS4A12
Membrane-spanning 4-domains subfamily A member 12; May be involved in signal transduction as a component of a multimeric receptor complex; Belongs to the MS4A family.
