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

CRYGSGamma-crystallin S; Crystallins are the dominant structural components of the vertebrate eye lens; Belongs to the beta/gamma-crystallin family. (178 aa)    
Predicted Functional Partners:
CRYAA
Alpha-crystallin A2(1-162); Contributes 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.
   
  
 0.960
BFSP2
Phakinin; Required for the correct formation and organization of lens intermediate filaments as part of a complex composed of BFSP1, BFSP2 and CRYAA.
      
 0.925
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.
   
 
 0.924
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.
      
 0.922
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 (By similarity). They are formed by the docking of two hexameric hemichannels, one from each cell membrane. 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.
      
 0.921
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. Involved in altering the calcium regulation of MIP water permeability.
   
  
 0.803
PITX3
Pituitary homeobox 3; Transcriptional regulator which is important for the differentiation and maintenance of meso-diencephalic dopaminergic (mdDA) neurons during development. In addition to its importance during development, it also has roles in the long-term survival and maintenance of the mdDA neurons. Activates NR4A2/NURR1-mediated transcription of genes such as SLC6A3, SLC18A2, TH and DRD2 which are essential for development of mdDA neurons. Acts by decreasing the interaction of NR4A2/NURR1 with the corepressor NCOR2/SMRT which acts through histone deacetylases (HDACs) to keep pro [...]
      
 0.802
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.
   
  
 0.795
HSF4
Heat shock factor protein 4; DNA-binding protein that specifically binds heat shock promoter elements (HSE). Isoform HSF4A represses transcription while the isoform HSF4B activates transcription. Belongs to the HSF family.
   
  
 0.705
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; Belongs to the PMP-22/EMP/MP20 family.
