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

CRYBB2Beta-crystallin B2; Crystallins are the dominant structural components of the vertebrate eye lens. (205 aa)    
Predicted Functional Partners:
CRYAA
Alpha-crystallin A(1-168); Contributes to the transparency and refractive index of the lens (By similarity). Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions. Required for the correct formation of lens intermediate filaments as part of a complex composed of BFSP1, BFSP2 and CRYAA (By similarity); Belongs to the small heat shock protein (HSP20) family.
   
 
 0.956
GJA3
Gap junction alpha-3 protein; Structural component of lens fiber 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 ; Belongs to the connexin family. Alpha-type (group II) subfamily.
  
   
 0.887
GJA8
Gap junction 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.
      
 0.866
CRYAB
Alpha-crystallin B chain; May contribute to the transparency and refractive index of the lens. Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions; Belongs to the small heat shock protein (HSP20) family.
   
 
 0.856
BFSP2
Phakinin C-terminal fragment; Required for the correct formation and organization of lens intermediate filaments as part of a complex composed of BFSP1, BFSP2 and CRYAA.
   
  
 0.806
MIP
Lens fiber major intrinsic protein; Water channel. Channel activity is down- regulated by CALM when cytoplasmic Ca(2+) levels are increased. May be responsible for regulating the osmolarity of the lens. Interactions between homotetramers from adjoining membranes may stabilize cell junctions in the eye lens core (By similarity). Plays a role in cell- to-cell adhesion and facilitates gap junction coupling. Belongs to the MIP/aquaporin (TC 1.A.8) family.
   
 
 0.762
BFSP1
Filensin C-terminal fragment; Required for the correct formation of lens intermediate filaments as part of a complex composed of BFSP1, BFSP2 and CRYAA (By similarity). Involved in altering the calcium regulation of MIP water permeability (By similarity).
   
  
 0.746
LIM2
Lens fiber membrane intrinsic protein; Present in the thicker 16-17 nm junctions of mammalian lens fiber cells, where it may contribute to cell junctional organization. Acts as a receptor for calmodulin. May play an important role in both lens development and cataractogenesis.
   
  
 0.742
PITX3
Homeobox protein.
      
 0.725
TMEM114
Transmembrane protein 114.
      
 0.694
