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.

PIGSGPI transamidase component PIG-S; Component of the GPI transamidase complex. Essential for transfer of GPI to proteins, particularly for formation of carbonyl intermediates. (555 aa)    
Predicted Functional Partners:
PIGU
Phosphatidylinositol glycan anchor biosynthesis class U protein; Component of the GPI transamidase complex. May be involved in the recognition of either the GPI attachment signal or the lipid portion of GPI.
   
 0.999
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.
   
 0.999
GPAA1
Glycosylphosphatidylinositol anchor attachment 1 protein; Essential for GPI-anchoring of precursor proteins but not for GPI synthesis. Acts before or during formation of the carbonyl intermediate.
   
 0.999
PIGK
GPI-anchor transamidase; Mediates GPI anchoring in the endoplasmic reticulum, by replacing a protein's C-terminal GPI attachment signal peptide with a pre-assembled GPI. During this transamidation reaction, the GPI transamidase forms a carbonyl intermediate with the substrate protein; Belongs to the peptidase C13 family.
   
 0.999
PIGG
GPI ethanolamine phosphate transferase 2; Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the GPI second mannose.
   
 0.944
PGAP1
GPI inositol-deacylase; Involved in inositol deacylation of GPI-anchored proteins. GPI inositol deacylation may important for efficient transport of GPI- anchored proteins from the endoplasmic reticulum to the Golgi (By similarity).
    
 0.938
PIGF
Phosphatidylinositol-glycan biosynthesis class F protein; Involved in GPI-anchor biosynthesis through the transfer of ethanolamine phosphate to the third mannose of GPI.
   
 
 0.917
PRSS50
Probable threonine protease PRSS50; May be involved in proteolysis through its threonine endopeptidase activity; Belongs to the peptidase S1 family.
    
   0.879
CASP9
Caspase-9 subunit p10; Involved in the activation cascade of caspases responsible for apoptosis execution. Binding of caspase-9 to Apaf-1 leads to activation of the protease which then cleaves and activates caspase-3. Promotes DNA damage-induced apoptosis in a ABL1/c-Abl-dependent manner. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP); Belongs to the peptidase C14A family.
   
 
 0.737
OVCA2
OVCA2 serine hydrolase domain containing; Belongs to the LovG family.
   
   0.690
