STRINGSTRING
SCT1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SCT1" - Glycerol 3-phosphate/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase of the glycerolipid biosynthesis pathway, prefers 16-carbon fatty acids, similar to Gpt2p, gene is constitutively transcribed 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

SCT1Glycerol 3-phosphate/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase of the glycerolipid biosynthesis pathway, prefers 16-carbon fatty acids, similar to Gpt2p, gene is constitutively transcribed; G-3-P/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase (759 aa)    
Predicted Functional Partners:
GPD2
NAD-dependent glycerol 3-phosphate dehydrogenase, homolog of Gpd1p, expression is controlled by an oxygen-independent signaling pathway required to regulate metabolism under anoxic conditions; located in cytosol and mitochondria; Catalyzes the production of glycerol under anaerobic growth conditions. Glycerol production serves as a redox sink by consuming the excess cytosolic NADH during anaerobic metabolism (440 aa)
   
 
  0.978
GPD1
NAD-dependent glycerol-3-phosphate dehydrogenase, key enzyme of glycerol synthesis, essential for growth under osmotic stress; expression regulated by high-osmolarity glycerol response pathway; homolog of Gpd2p; Catalyzes the production and accumulation of glycerol during hyperosmotic stress conditions. Glycerol acts as a osmoregulator that prevents loss of water and turgor of the cells (391 aa)
   
 
  0.978
ALE1
Broad-specificity lysophospholipid acyltransferase, part of MBOAT family of membrane-bound O-acyltransferases; key component of Lands cycle; may have role in fatty acid exchange at sn-2 position of mature glycerophospholipids; Membrane-bound O-acyltransferase that mediates the incorporation of unsaturated acyl chains into the sn-2 position of phospholipids. Preferentially acylates lysophosphocholine, but also lysophosphoethanolamine and lysophosphatidylglycerol (619 aa)
     
  0.971
AYR1
NADPH-dependent 1-acyl dihydroxyacetone phosphate reductase found in lipid particles, ER, and mitochondrial outer membrane; involved in phosphatidic acid biosynthesis; required for spore germination; capable of metabolizing steroid hormones; Can convert acyl and alkyl dihydroxyacetone-phosphate (DHAP) into glycerolipids and ether lipids, respectively. Required for the biosynthesis of phosphatidic acid via the DHAP pathway, where it reduces 1-acyl DHAP to lysophosphatidic acid (LPA). Required for spore germination (297 aa)
     
  0.960
TGL4
Multifunctional triacylglycerol lipase, steryl ester hydrolase, and Ca2+-independent phospholipase A2; catalyzes acyl-CoA dependent acylation of LPA to PA; required with Tgl3p for timely bud formation; phosphorylated and activated by Cdc28p; Releases specific fatty acids from neutral lipid triacylglycerols (TAG) thereby supplying fatty acids to a general acylation process. May have a specific role in sporulation (910 aa)
   
 
  0.957
PAH1
Mg<sup>2+</sup>-dependent phosphatidate (PA) phosphatase, catalyzes the dephosphorylation of PA to yield diacylglycerol, responsible for de novo lipid synthesis and formation of lipid droplets; homologous to mammalian lipin 1; Mg(2+)-dependent phosphatidate (PA) phosphatase which catalyzes the dephosphorylation of PA to yield diacylglycerol. Required for de novo lipid synthesis and formation of lipid droplets. Controles transcription of phospholipid biosynthetic genes and nuclear structure by regulating the amount of membrane present at the nuclear envelope. Involved in plasmid mainten [...] (862 aa)

TGL5
Bifunctional enzyme with triacylglycerol lipase and lysophosphatidic acid acyltransferase activity; involved in triacylglycerol mobilization; localizes to lipid particles; potential Cdc28p substrate; Releases specific fatty acids from neutral lipid triacylglycerols (TAG) thereby supplying fatty acids to a general acylation process. May have a specific role in sporulation (749 aa)

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)

LOA1
Lysophosphatidic acid acyltransferase; involved in triacelglyceride homeostasis and lipid droplet formation; localized to lipid droplets and the ER; specificity for oleoyl-CoA; Acyl-CoA-dependent lysophosphatidic acid acyltransferase with preference for oleoyl-CoA. Involved in triacylglyceride homeostasis and lipid droplet formation. Involved in vacuolar protein sorting (300 aa)

SLC1
1-acyl-sn-glycerol-3-phosphate acyltransferase, catalyzes the acylation of lysophosphatidic acid to form phosphatidic acid, a key intermediate in lipid metabolism; enzymatic activity detected in lipid particles and microsomes; May be an acyltransferase with an altered substrate specificity that enables it to use a C-26-CoA in place of the C-16 or C-18-CoAs used by the wild-type protein (303 aa)
