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:
some 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

SFTPCPulmonary 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; BRICHOS domain containing (197 aa)    
Predicted Functional Partners:
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
   
 
 0.982
SFTPA2
Pulmonary surfactant-associated protein A2; 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; C-type lectin domain containing
   
 
 0.981
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); Belongs to the SFTPA family
   
 
 0.980
PIGR
Polymeric immunoglobulin receptor; This receptor binds polymeric IgA and IgM at the basolateral surface of epithelial cells. The complex is then transported across the cell to be secreted at the apical surface. During this process a cleavage occurs that separates the extracellular (known as the secretory component) from the transmembrane segment; V-set domain containing
      
 0.974
NAPSA
Napsin a aspartic peptidase; Napsin-A; May be involved in processing of pneumocyte surfactant precursors
   
 
 0.938
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; C-type lectin domain containing
   
 
 0.932
CTSH
Pro-cathepsin H; Important for the overall degradation of proteins in lysosomes; Belongs to the peptidase C1 family
     
 0.930
TTF1
Transcription termination factor 1; Multifunctional nucleolar protein that terminates ribosomal gene transcription, mediates replication fork arrest and regulates RNA polymerase I transcription on chromatin. Plays a dual role in rDNA regulation, being involved in both activation and silencing of rDNA transcription. Interaction with BAZ2A/TIP5 recovers DNA-binding activity; Myb/SANT domain containing
     
 0.921
GPR116
Adhesion G protein-coupled receptor F5; Receptor that plays a critical role in lung surfactant homeostasis. May play a role in controlling adipocyte function; Belongs to the G-protein coupled receptor 2 family. Adhesion G-protein coupled receptor (ADGR) subfamily
   
 
 0.918
ADORA2B
Adenosine receptor A2b; Receptor for adenosine. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase
     
 0.904
