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

SFTA2Surfactant-associated protein 2; Putative surfactant protein. (78 aa)    
Predicted Functional Partners:
SFTA3
Surfactant-associated protein 3; Putative surfactant protein. May be involved in wound healing and in the reduction of the surface tension at the ocular surface.
   
  
 0.649
SFTPA1
Pulmonary surfactant-associated protein A1; In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air- liquid interface in the alveoli of the mammalian lung and is essential for normal respiration. Enhances the expression of MYO18A/SP-R210 on alveolar macrophages (By similarity).
   
  
 0.632
MUCL3
Mucin-like protein 3; May modulate NF-kappaB signaling and play a role in cell growth.
   
  
 0.544
SFTPA2
Surfactant protein A2.
   
  
 0.515
SFTPC
Pulmonary surfactant-associated protein C; Pulmonary surfactant associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces.
   
  
 0.505
SCGB3A2
Secretoglobin family 3A member 2; Secreted cytokine-like protein. Binds to the scavenger receptor MARCO. Can also bind to pathogens including the Gram-positive bacterium L.monocytogenes, the Gram-negative bacterium P.aeruginosa, and yeast. Strongly inhibits phospholipase A2 (PLA2G1B) activity. Seems to have anti-inflammatory effects in respiratory epithelium (By similarity). Also has anti-fibrotic activity in lung. May play a role in fetal lung development and maturation. Promotes branching morphogenesis during early stages of lung development. In the pituitary, may inhibit production [...]

SFTPB
Pulmonary surfactant-associated protein B; Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter.
   
  
 0.453
SFTPD
Pulmonary surfactant-associated protein D; Contributes to the lung's defense against inhaled microorganisms, organic antigens and toxins. Interacts with compounds such as bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune response. May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha- glucosyl moieties.
   
  
 0.447
VARS1
Valine--tRNA ligase; valyl-tRNA synthetase 1; Belongs to the class-I aminoacyl-tRNA synthetase family.
      
 0.447
VARS2
Valine--tRNA ligase, mitochondrial; valyl-tRNA synthetase 2, mitochondrial.
      
 0.418
