STRINGSTRING
ARV1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ARV1" - Protein functioning in transport of glycosylphosphatidylinositol intermediates into ER lumen in Saccharomyces cerevisiae
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ARV1Protein functioning in transport of glycosylphosphatidylinositol intermediates into ER lumen; required for normal intracellular sterol distribution; human ARV1 required for normal cholesterol and bile acid homeostasis; similar to Nup120p; Mediator of sterol homeostasis involved in sterol uptake, trafficking and distribution into membranes. Regulates also the sphingolipid metabolism. Required for growth during anaerobiosis and sterol uptake (321 aa)    
Predicted Functional Partners:
GWT1
Protein involved in the inositol acylation of glucosaminyl phosphatidylinositol (GlcN-PI) to form glucosaminyl(acyl)phosphatidylinositol (GlcN(acyl)PI), an intermediate in the biosynthesis of glycosylphosphatidylinositol (GPI) anchors; 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 (490 aa)
       
 
  0.806
GAA1
Subunit of the GPI (glycosylphosphatidylinositol)-protein transamidase complex, removes the GPI-anchoring signal and attaches GPI to proteins in the ER; Component of the GPI transamidase complex. Required for a terminal step of GPI anchor attachment onto proteins. Affects endocytosis (614 aa)
       
 
  0.768
LAS21
Integral plasma membrane protein involved in the synthesis of the glycosylphosphatidylinositol (GPI) core structure; mutations affect cell wall integrity; Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the GPI second mannose. Although not essential, addition of ethanolamine phosphate to the second mannose plays an important role in cell separation via the GPI- based modification of daughter-specific proteins (830 aa)
       
 
  0.748
ARE2
Acyl-CoA-sterol acyltransferase, isozyme of Are1p; endoplasmic reticulum enzyme that contributes the major sterol esterification activity in the presence of oxygen; Ensures probably most of the acyltransferase activity. Suppression of ARE2 reduces sterol ester levels to 25% of the normal value (642 aa)
       
 
  0.744
GPI15
Protein involved in the synthesis of N-acetylglucosaminyl phosphatidylinositol (GlcNAc-PI), the first intermediate in the synthesis of glycosylphosphatidylinositol (GPI) anchors; homologous to the human PIG-H protein; Part of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis (229 aa)
       
 
  0.727
SPT14
UDP-GlcNAc-binding and catalytic subunit of the enzyme that mediates the first step in glycosylphosphatidylinositol (GPI) biosynthesis, mutations cause defects in transcription and in biogenesis of cell wall proteins; Catalytic subunit in the complex catalyzing the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis (452 aa)
       
 
  0.712
GPI1
Membrane protein involved in the synthesis of N-acetylglucosaminyl phosphatidylinositol (GlcNAc-PI), the first intermediate in the synthesis of glycosylphosphatidylinositol (GPI) anchors; human and mouse GPI1p are functional homologs; Part of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis (609 aa)
     
 
  0.688
GPI2
Protein involved in the synthesis of N-acetylglucosaminyl phosphatidylinositol (GlcNAc-PI), the first intermediate in the synthesis of glycosylphosphatidylinositol (GPI) anchors; homologous to the human PIG-C protein; Part of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis (280 aa)
     
 
  0.688
RSM23
Mitochondrial ribosomal protein of the small subunit, has similarity to mammalian apoptosis mediator proteins; null mutation prevents induction of apoptosis by overproduction of metacaspase Mca1p; Required for maintenance of mitochondrial DNA (450 aa)
       
 
  0.682
HAC1
Basic leucine zipper (bZIP) transcription factor (ATF/CREB1 homolog) that regulates the unfolded protein response, via UPRE binding, and membrane biogenesis; ER stress-induced splicing pathway facilitates efficient Hac1p synthesis; Transcriptional activator involved in the unfolded protein response (UPR) pathway. Recognizes and binds to the UPR element (UPRE) in the promoter of UPR-regulated genes such as KAR2, PDI1, EUG1 and FKB2. Increases the synthesis of endoplasmic reticulum-resident proteins required for protein folding as well as components of the secretory pathway (238 aa)
