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

PtgfrnProstaglandin F2 receptor negative regulator; Inhibits the binding of prostaglandin F2-alpha (PGF2-alpha) to its specific FP receptor, by decreasing the receptor number rather than the affinity constant. Functional coupling with the prostaglandin F2-alpha receptor seems to occur (By similarity). In myoblasts, associates with tetraspanins CD9 and CD81 to prevent myotube fusion during muscle regeneration. (879 aa)    
Predicted Functional Partners:
Cd9
CD9 antigen; Integral membrane protein associated with integrins, which regulates different processes, such as sperm-egg fusion, platelet activation and aggregation, and cell adhesion. Present at the cell surface of oocytes and plays a key role in sperm-egg fusion, possibly by organizing multiprotein complexes and the morphology of the membrane required for the fusion. In myoblasts, associates with CD81 and PTGFRN and inhibits myotube fusion during muscle regeneration. In macrophages, associates with CD9 and beta-1 and beta-2 integrins, and prevents macrophage fusion into multinucleate [...]
    
 
 0.997
Cd81
CD81 antigen; Structural component of specialized membrane microdomains known as tetraspanin-enriched microdomains (TERMs), which act as platforms for receptor clustering and signaling. Essential for trafficking and compartmentalization of CD19 receptor on the cell surface of activated B cells. Upon initial encounter with a microbial pathogen, enables the assembly of CD19-CR2 and B cell receptor complexes at signaling TERMs, lowering the threshold dose of antigen required to trigger B cell clonal expansion and humoral immune response (By similarity). In T cells, associates with CD4 or [...]
    
 
 0.995
Tspan3
Tetraspanin-3; Regulates the proliferation and migration of oligodendrocytes, a process essential for normal myelination and repair.
    
 
 0.871
Cd151
CD151 antigen; Essential for the proper assembly of the glomerular and tubular basement membranes in kidney; Belongs to the tetraspanin (TM4SF) family.
   
 
 0.840
Ezr
Ezrin; Probably involved in connections of major cytoskeletal structures to the plasma membrane. In epithelial cells, required for the formation of microvilli and membrane ruffles on the apical pole. Along with PLEKHG6, required for normal macropinocytosis (By similarity).
   
  
 0.812
Tspan18
Tetraspanin-18.
   
 
 0.767
Tspan15
Tetraspanin-15; Regulates maturation and trafficking of the transmembrane metalloprotease ADAM10. Promotes ADAM10-mediated cleavage of (CDH2). Negatively regulates ligand-induced Notch activity probably by regulating ADAM10 activity (By similarity); Belongs to the tetraspanin (TM4SF) family.
   
 
 0.714
Apmap
Adipocyte plasma membrane-associated protein; Exhibits strong arylesterase activity with beta-naphthyl acetate and phenyl acetate (By similarity). May play a role in adipocyte differentiation.
    
 
 0.689
Cd82
CD82 antigen; Associates with CD4 or CD8 and delivers costimulatory signals for the TCR/CD3 pathway; Belongs to the tetraspanin (TM4SF) family.
    
 
 0.662
Tspan33
Tetraspanin-33; Plays an important role in normal erythropoiesis. It has a role in the differentiation of erythroid progenitors. Regulates maturation and trafficking of the transmembrane metalloprotease ADAM10. Negatively regulates ligand-induced Notch activity probably by regulating ADAM10 activity (By similarity). Mediates docking of ADAM10 to zonula adherens by interacting with ADAM10 and, in a PDZD11-dependent manner, with the zonula adherens protein PLEKHA7.
