STRINGSTRING
SCS3 protein (Saccharomyces cerevisiae) - STRING interaction network
"SCS3" - Protein required for inositol prototrophy, identified as an ortholog of the FIT family of proteins involved in triglyceride droplet biosynthesis 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

SCS3Protein required for inositol prototrophy, identified as an ortholog of the FIT family of proteins involved in triglyceride droplet biosynthesis; disputed role in the synthesis of inositol phospholipids from inositol; Appears to be involved in the synthesis of inositol phospholipids from inositol (380 aa)    
Predicted Functional Partners:
DGK1
Diacylglycerol kinase, localized to the endoplasmic reticulum (ER); overproduction induces enlargement of ER-like membrane structures and suppresses a temperature-sensitive sly1 mutation; contains a CTP transferase domain; Involved in pre-tRNA splicing (By similarity). CTP- dependent diacylglycerol kinase that catalyzes the phosphorylation of diacylglycerol (DAG) to phosphatidate (PA). Controls phosphatidate levels at the nuclear envelope. Counteracts the activity of PAH1/SMP2. Involved in the resistance to nickel chloride and nalidixic acid. May be involved in vesicle trafficking betw [...] (290 aa)
       
 
  0.858
SEY1
GTPase with a role in ER morphology; interacts physically and genetically with Yop1p and Rtn1p; possible functional ortholog of mammalian atlastins, defects in which cause a form of hereditary spastic paraplegia; homolog of Arabidopsis RHD3; Cooperates with the reticulon proteins RTN1 and RTN2 and the tubule-shaping DP1 family protein YOP1 to generate and maintain the structure of the tubular endoplasmic reticulum network. Has GTPase activity, which is required for its function in ER organization (776 aa)
       
 
  0.842
ICE2
Integral ER membrane protein with type-III transmembrane domains; mutations cause defects in cortical ER morphology in both the mother and daughter cells (491 aa)
       
 
  0.710
VAC8
Phosphorylated and palmitoylated vacuolar membrane protein; interacts with Atg13p, required for the cytoplasm-to-vacuole targeting (Cvt) pathway; interacts with Nvj1p to form nucleus-vacuole junctions; Functions in both vacuole inheritance and protein targeting from the cytoplasm to vacuole (578 aa)
       
      0.666
YFT2
Putative protein of unknown function, identified as an ortholog of the highly conserved FIT family of proteins involved in triglyceride droplet biosynthesis; interacts with Sst2p and Hsp82p in high-throughput two-hybrid screens (274 aa)
           
  0.637
CSG2
Endoplasmic reticulum membrane protein, required for mannosylation of inositolphosphorylceramide and for growth at high calcium concentrations; Required for calcium regulation. May regulate calcium accumulation by a non-vacuole organelle. Also regulates the activity of CSH1 and SUR1 during mannosyl phosphorylinositol ceramide synthesis (410 aa)
       
      0.577
INO4
Transcription factor required for derepression of inositol-choline-regulated genes involved in phospholipid synthesis; forms a complex, with Ino2p, that binds the inositol-choline-responsive element through a basic helix-loop-helix domain; Transcriptional activator of phospholipid synthetic genes (such as INO1, CHO1/PSS, CHO2/PEM1, OPI3/PEM2, etc.) (151 aa)
       
 
  0.464
IRE1
Serine-threonine kinase and endoribonuclease; transmembrane protein that mediates the unfolded protein response (UPR) by regulating Hac1p synthesis through HAC1 mRNA splicing; Kar2p binds inactive Ire1p and releases from it upon ER stress; Senses unfolded proteins in the lumen of the endoplasmic reticulum via its N-terminal domain which leads to enzyme auto- activation. The active endoribonuclease domain splices HAC1 precursor mRNA to produce the mature form which then induces transcription of UPR target genes (1115 aa)
       
 
  0.445
INO2
Component of the heteromeric Ino2p/Ino4p basic helix-loop-helix transcription activator that binds inositol/choline-responsive elements (ICREs), required for derepression of phospholipid biosynthetic genes in response to inositol depletion; Positive regulatory factor required for depression of the coregulated phospholipid biosynthetic enzymes. Also involved in the expression of ITR1 (304 aa)
           
  0.440
SCS2
Integral ER membrane protein that regulates phospholipid metabolism via an interaction with the FFAT motif of Opi1p, also involved in telomeric silencing, disruption causes inositol auxotrophy above 34 degrees C, VAP homolog; Targets proteins containing a FFAT motif to endoplasmic reticulum membranes. Regulates phospholipid biosynthesis by modulating the subcellular localization of the transcriptional repressor OPI1 (244 aa)
