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

Predicted Functional Partners:
scp1
Sterol regulatory element-binding protein cleavage-activating protein; Escort protein required for sre1 processing at low sterol as well as oxygen levels. May regulate export of the scp1/sre1 complex from the ER at low sterol or oxygen levels. 4-methyl sterols bound to scp1 may mask an ER-export signal in scp1 leading to retention of the complex in the ER. Release of 4-methyl sterols may trigger a conformational change in the SSC domain of scp1 unmasking the ER export signal leading to recruitment into COPII-coated vesicles, transport to the Golgi complex, proteolytic cleavage of sre1 [...]

hmg1
3-hydroxy-3-methylglutaryl-coenzyme A reductase; Catalyzes the conversion of HMG-CoA to mevalonate. It is the rate-limiting enzyme of the sterol biosynthesis pathway. Involved in ergosterol biosynthesis.
   
 
 0.950
sre1
Processed sterol regulatory element-binding protein 1; Transcriptional activator required for transcription of genes required for adaptation to anaerobic growth like those implicated in the nonrespiratory oxygen-consumptive biosynthetic pathways of sterol, heme, sphingolipid, and ubiquinone biosynthesis. May monitor oxygen levels through sterol synthesis steps which require oxygen.
   
 
 0.662
gwt1
GPI-anchored wall transfer protein 1; Probable acetyltransferase, which acetylates the inositol ring of phosphatidylinositol during biosynthesis of GPI-anchor (By similarity). Has a role in meiosis.
   
  
 0.613
orc5
Origin recognition complex subunit 5; Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. ORC binds to multiple sites within the ars1 origin of DNA replication in an ATP-independent manner.
    
   0.607
orc6
Origin recognition complex subunit 6; Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. ORC binds to multiple sites within the ars1 origin of DNA replication in an ATP-independent manner.
    
   0.607
orc3
Origin recognition complex subunit 3; Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. ORC binds to multiple sites within the ars1 origin of DNA replication in an ATP-independent manner.
    
   0.607
erg11
Lanosterol 14-alpha demethylase erg11; Catalyzes C14-demethylation of lanosterol which is critical for ergosterol biosynthesis. It transforms lanosterol into 4,4'- dimethyl cholesta-8,14,24-triene-3-beta-ol.
   
  
 0.548
hrd1
ERAD-associated E3 ubiquitin-protein ligase hrd1; E3 ubiquitin-protein ligase which accepts ubiquitin specifically from endoplasmic reticulum-associated E2 ligases, and transfers it to substrates promoting their degradation. Mediates the degradation of endoplasmic reticulum proteins (ERQC), also called ER- associated degradation (ERAD). Component of the hrd1 ubiquitin ligase complex, which is part of the ERAD-L and ERAD-M pathways responsible for the rapid degradation of soluble lumenal and membrane proteins with misfolded lumenal domains (ERAD-L), or ER-membrane proteins with misfolde [...]
