STRINGSTRING
LAS21 protein (Saccharomyces cerevisiae) - STRING interaction network
"LAS21" - Integral plasma membrane protein involved in the synthesis of the glycosylphosphatidylinositol 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

LAS21Integral 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)    
Predicted Functional Partners:
GPI8
ER membrane glycoprotein subunit of the GPI transamidase complex; adds glycosylphosphatidylinositol (GPI) anchors to newly synthesized proteins; human PIG-K protein is a functional homolog; 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 (411 aa)
     
 
  0.933
ERV25
Protein that forms a heterotrimeric complex with Erp1, Erp2p, and Emp24, member of the p24 family involved in endoplasmic reticulum to Golgi transport; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles. Required for efficient transport of a subset of secretory proteins to the Golgi. Possesses a C-terminal dilysine motif that interacts with COPI coat subunits. Facilitates retrograde transport from the Golgi to the endoplasmic reticulum (211 aa)
       
 
  0.870
GPI10
Integral membrane protein involved in GPI anchor synthesis; putative alpha 1,2 mannosyltransferase required for addition of the third mannose onto the glycosylphosphatidylinositol (GPI) core structure; human PIG-Bp is a functional homolog; Mannosyltransferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers the third mannose to Man2-GlcN-acyl-PI during GPI precursor assembly (616 aa)
     
 
  0.862
FUI1
High affinity uridine permease, localizes to the plasma membrane; also mediates low but significant transport of the cytotoxic nucleoside analog 5-fluorouridine; not involved in uracil transport; High-affinity transport of uridine (639 aa)
       
 
  0.846
ECM33
GPI-anchored protein of unknown function, has a possible role in apical bud growth; GPI-anchoring on the plasma membrane crucial to function; phosphorylated in mitochondria; similar to Sps2p and Pst1p; Required for proper cell wall integrity and for the correct assembly of the mannoprotein outer layer of the cell wall. Important for apical bud growth (429 aa)
       
 
  0.844
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)
     
 
  0.843
ELO3
Elongase, involved in fatty acid and sphingolipid biosynthesis; synthesizes very long chain 20-26-carbon fatty acids from C18-CoA primers; involved in regulation of sphingolipid biosynthesis; Component of a microsomal membrane bound long-chain fatty acid elongation system, which produces the 20-26-carbon very long-chain fatty acids (VLCFA) from long-chain fatty acid precursors and is involved ceramide and inositol sphingolipid biosynthesis. Component of elongase III, which synthesizes 20-26- carbon fatty acids from 18-carbon-fatty acyl-CoA primers such as stearoyl-CoA by incorporation [...] (345 aa)
       
 
  0.840
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)
     
 
  0.836
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)
     
 
  0.820
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)
