STRINGSTRING
TSC3 protein (Saccharomyces cerevisiae) - STRING interaction network
"TSC3" - Protein that stimulates the activity of serine palmitoyltransferase (Lcb1p, Lcb2p) several-fold 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

TSC3Protein that stimulates the activity of serine palmitoyltransferase (Lcb1p, Lcb2p) several-fold; involved in sphingolipid biosynthesis; Stimulates the activity of serine palmitoyltransferase (SPT) (80 aa)    
Predicted Functional Partners:
LCB2
Component of serine palmitoyltransferase, responsible along with Lcb1p for the first committed step in sphingolipid synthesis, which is the condensation of serine with palmitoyl-CoA to form 3-ketosphinganine; Catalytic subunit of serine palmitoyltransferase (SPT), which catalyzes the committed step in the synthesis of sphingolipids, the condensation of serine with palmitoyl CoA to form the long chain base 3-ketosphinganine (561 aa)
       
  0.994
LCB1
Component of serine palmitoyltransferase, responsible along with Lcb2p for the first committed step in sphingolipid synthesis, which is the condensation of serine with palmitoyl-CoA to form 3-ketosphinganine; Component of serine palmitoyltransferase (SPT), which catalyzes the committed step in the synthesis of sphingolipids, the condensation of serine with palmitoyl CoA to form the long chain base 3-ketosphinganine (558 aa)
       
  0.992
ORM2
Evolutionarily conserved protein, similar to Orm1p, required for resistance to agents that induce unfolded protein response; Orm1p and Orm2p together control membrane biogenesis by coordinating lipid homeostasis with protein quality control; Component of the SPOTS complex that acts as a negative regulator of sphingolipid synthesis. Acts by inhibiting serine palmitoyltransferases (LCB1 and LCB2) activity (216 aa)
       
  0.950
SAC1
Phosphatidylinositol phosphate (PtdInsP) phosphatase involved in hydrolysis of PtdIns[4]P; transmembrane protein localizes to ER and Golgi; involved in protein trafficking and processing, secretion, and cell wall maintenance; Phosphoinositide phosphatase that hydrolyzes PtdIns(3)P and PtdIns(4)P. Has low activity towards PtdIns(3,5)P2. May be involved in the coordination of the activities of the secretory pathway and the actin cytoskeleton (623 aa)
         
  0.937
ORM1
Evolutionarily conserved protein, similar to Orm2p, required for resistance to agents that induce unfolded protein response; Orm1p and Orm2p together control membrane biogenesis by coordinating lipid homeostasis with protein quality control; Component of the SPOTS complex that acts as a negative regulator of sphingolipid synthesis. Acts by inhibiting serine palmitoyltransferases (LCB1 and LCB2) activity (222 aa)
       
  0.936
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)
       
 
  0.894
TSC10
3-ketosphinganine reductase, catalyzes the second step in phytosphingosine synthesis, essential for growth in the absence of exogenous dihydrosphingosine or phytosphingosine, member of short chain dehydrogenase/reductase protein family; Catalyzes the reduction of 3-ketodihydrosphingosine (KDS) to dihydrosphingosine (DHS) (320 aa)
           
  0.890
SUR2
Sphinganine C4-hydroxylase, catalyses the conversion of sphinganine to phytosphingosine in sphingolipid biosyntheis; Required for hydroxylation of C-4 in the sphingoid moiety of ceramide. Involved in the response to syringomycin (349 aa)
           
  0.740
SHR5
Subunit of a palmitoyltransferase, composed of Shr5p and Erf2p, that adds a palmitoyl lipid moiety to heterolipidated substrates such as Ras1p and Ras2p through a thioester linkage; palmitoylation is required for Ras2p membrane localization; The ERF2-SHR5 complex is a palmitoyltransferase specific for Ras proteins. Palmitoylates RAS2, which is required for its proper plasma membrane localization (237 aa)
         
  0.727
ISC1
Mitochondrial membrane localized inositol phosphosphingolipid phospholipase C, hydrolyzes complex sphingolipids to produce ceramide; activated by phosphatidylserine, cardiolipin, and phosphatidylglycerol; mediates Na+ and Li+ halotolerance; Responsible for the hydrolysis of the phosphosphingolipids (IPS), inositol phosphorylceramide (IPC), mannosylinositol phosphorylceramide (MIPC), and mannosyldiinositol phosphorylceramide (M(IP)2C). Also active on sphingomyelin, but this activity is probably not physiologically relevant (477 aa)
