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.

TJP3Tight junction protein ZO-3; TJP1, TJP2, and TJP3 are closely related scaffolding proteins that link tight junction (TJ) transmembrane proteins such as claudins, junctional adhesion molecules, and occludin to the actin cytoskeleton. The tight junction acts to limit movement of substances through the paracellular space and as a boundary between the compositionally distinct apical and basolateral plasma membrane domains of epithelial and endothelial cells. Binds and recruits PATJ to tight junctions where it connects and stabilizes apical and lateral components of tight junctions. Promote [...] (928 aa)    
Predicted Functional Partners:
CLDN1
Claudin-1; Claudins function as major constituents of the tight junction complexes that regulate the permeability of epithelia. While some claudin family members play essential roles in the formation of impermeable barriers, others mediate the permeability to ions and small molecules. Often, several claudin family members are coexpressed and interact with each other, and this determines the overall permeability. CLDN1 is required to prevent the paracellular diffusion of small molecules through tight junctions in the epidermis and is required for the normal barrier function of the skin. [...]

PATJ
InaD-like protein; Scaffolding protein that may bring different proteins into adjacent positions at the cell membrane (Probable). May regulate protein targeting, cell polarity and integrity of tight junctions. May regulate the surface expression and/or function of ASIC3 in sensory neurons (By similarity). May recruit ARHGEF18 to apical cell-cell boundaries.
   
0.971
CLDN8
Claudin-8; Tight-junction protein required for paracellular chloride transport in the kidney. Mediates recruitment of CLDN4 to tight junction in the kidney. Claudins play a major role in tight junction- specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity.
   
 
 0.951
CGN
Cingulin; Probably plays a role in the formation and regulation of the tight junction (TJ) paracellular permeability barrier; Belongs to the cingulin family.
   
 
 0.947
CLDN7
Claudin-7; Plays a major role in tight junction-specific obliteration of the intercellular space; Belongs to the claudin family.
   
 0.917
CLDN3
Claudin-3; Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity; Belongs to the claudin family.
   
 
 0.907
OCLN
Occludin; May play a role in the formation and regulation of the tight junction (TJ) paracellular permeability barrier. It is able to induce adhesion when expressed in cells lacking tight junctions.
   
  
 0.902
CLDN4
Claudin-4; Channel-forming tight junction protein that mediates paracellular chloride transport in the kidney. Plays a critical role in the paracellular reabsorption of filtered chloride in the kidney collecting ducts. Claudins play a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity; Belongs to the claudin family.

CLDN2
Claudin-2; Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.
   
 0.868
CLDN5
Claudin-5; Plays a major role in tight junction-specific obliteration of the intercellular space.
