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

PGAP4Transmembrane protein 246; post-GPI attachment to proteins GalNAc transferase 4. (403 aa)    
Predicted Functional Partners:
PIGZ
GPI mannosyltransferase 4; Mannosyltransferase involved in glycosylphosphatidylinositol- anchor biosynthesis. Transfers a fourth mannose to some trimannosyl- GPIs during GPI precursor assembly. The presence of a fourth mannose in GPI is facultative and only scarcely detected, suggesting that it only exists in some tissues; Belongs to the glycosyltransferase 22 family. PIGZ subfamily.
   
  
 0.669
PIGO
GPI ethanolamine phosphate transferase 3; Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the GPI third mannose which links the GPI- anchor to the C-terminus of the proteins by an amide bond. Belongs to the PIGG/PIGN/PIGO family. PIGO subfamily.
      
 0.541
B3GALT4
Beta-1,3-galactosyltransferase 4; Involved in GM1/GD1B/GA1 ganglioside biosynthesis.
      
 0.507
FREM1
FRAS1-related extracellular matrix protein 1; Extracellular matrix protein that plays a role in epidermal differentiation and is required for epidermal adhesion during embryonic development; Belongs to the FRAS1 family.
   
  
 0.462
WDR31
WD repeat domain 31.
      
 0.460
PGAP3
Post-GPI attachment to proteins factor 3; Involved in the lipid remodeling steps of GPI-anchor maturation. Lipid remodeling steps consist in the generation of 2 saturated fatty chains at the sn-2 position of GPI-anchors proteins. Required for phospholipase A2 activity that removes an acyl-chain at the sn-2 position of GPI-anchors during the remodeling of GPI (Probable); Belongs to the PGAP3 family.
      
 0.448
PIGB
GPI mannosyltransferase 3; Mannosyltransferase involved in glycosylphosphatidylinositol- anchor biosynthesis. Transfers the third alpha-1,2-mannose to Man2- GlcN-acyl-PI during GPI precursor assembly. Belongs to the glycosyltransferase 22 family. PIGB subfamily.
      
 0.446
PIGS
GPI transamidase component PIG-S; Component of the GPI transamidase complex. Essential for transfer of GPI to proteins, particularly for formation of carbonyl intermediates.
      
 0.417
PGAP2
Post-GPI attachment to proteins factor 2; Involved in the lipid remodeling steps of GPI-anchor maturation. Required for stable expression of GPI-anchored proteins at the cell surface (By similarity); Belongs to the PGAP2 family.
      
 0.416
ST3GAL5
Lactosylceramide alpha-2,3-sialyltransferase; Catalyzes the formation of ganglioside GM3 (alpha-N- acetylneuraminyl-2,3-beta-D-galactosyl-1, 4-beta-D-glucosylceramide).
