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

PIGWPhosphatidylinositol-glycan biosynthesis class W protein; Required for the transport of GPI-anchored proteins to the plasma membrane. Probable acetyltransferase, which acetylates the inositol ring of phosphatidylinositol during biosynthesis of GPI-anchor. Acetylation during GPI-anchor biosynthesis is not essential for the subsequent mannosylation and is usually removed soon after the attachment of GPIs to proteins (By similarity). Belongs to the PIGW family. (504 aa)    
Predicted Functional Partners:
PIGL
N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase; Involved in the second step of GPI biosynthesis. De-N- acetylation of N-acetylglucosaminyl-phosphatidylinositol; Belongs to the PIGL family.
  
 
 0.991
PIGM
GPI mannosyltransferase 1; Mannosyltransferase involved in glycosylphosphatidylinositol- anchor biosynthesis. Transfers the first alpha-1,4-mannose to GlcN- acyl-PI during GPI precursor assembly; Belongs to the PIGM family.
   
 
 0.982
GPLD1
Phosphatidylinositol-glycan-specific phospholipase D; This protein hydrolyzes the inositol phosphate linkage in proteins anchored by phosphatidylinositol glycans (GPI-anchor) thus releasing these proteins from the membrane.
     
 0.929
PIGV
GPI mannosyltransferase 2; Alpha-1,6-mannosyltransferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers the second mannose to the glycosylphosphatidylinositol during GPI precursor assembly.
      
 0.878
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.
   
  
 0.837
PIGC
Phosphatidylinositol N-acetylglucosaminyltransferase subunit C; Involved in GPI anchor biosynthesis. Part of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis (ECO:0000269|. Belongs to the PIGC family.
   
 
 0.826
PIGQ
Phosphatidylinositol N-acetylglucosaminyltransferase subunit Q; Part of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis.
    
 
 0.825
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.
   
 
 0.825
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.
      
 0.809
PIGT
GPI transamidase component PIG-T; Component of the GPI transamidase complex. Essential for transfer of GPI to proteins, particularly for formation of carbonyl intermediates.
