STRINGSTRING
PSD1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PSD1" - Phosphatidylserine decarboxylase of the mitochondrial inner membrane, converts phosphatidylserine to phosphatidylethanolamine 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

PSD1Phosphatidylserine decarboxylase of the mitochondrial inner membrane, converts phosphatidylserine to phosphatidylethanolamine; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer). Plays a central role in phospholipid metabolism and in the interorganelle trafficking of phosphatidylserine (PubMed-8227017, PubMed-8407984, PubMed-17976194, PubMed-23124206, PubMed-25829489). Phosphatidylethanolamine formed in the mitochondria is exported to other membranes to fullfill their requirements for PtdEtn (PubMed-8530379, PubMed-11294902). Required for norm [...] (500 aa)    
Predicted Functional Partners:
CHO1
Phosphatidylserine synthase, functions in phospholipid biosynthesis; catalyzes the reaction CDP-diaclyglycerol + L-serine = CMP + L-1-phosphatidylserine, transcriptionally repressed by myo-inositol and choline (276 aa)
   
 
  0.997
CHO2
Phosphatidylethanolamine methyltransferase (PEMT), catalyzes the first step in the conversion of phosphatidylethanolamine to phosphatidylcholine during the methylation pathway of phosphatidylcholine biosynthesis; Catalyzes the first step in the conversion of phosphatidylethanolamine to phosphatidylcholine during the methylation pathway of phosphatidylcholine biosynthesis. Preferentially converts di-C16-1 substrates (869 aa)
     
  0.989
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)
     
  0.983
EPT1
Sn-1,2-diacylglycerol ethanolamine- and cholinephosphotranferase; not essential for viability; Catalyzes the final step in the CDP-ethanolamine route leading to phosphatidylethanolamine (PE). Can also catalyze the formation of phosphatidylcholine (PC) from CDP-choline, but does not substantially contribute to PC biosynthesis. Preferentially uses CDP-dimethylethanolamine and CDP-propanolamine as aminoalcohol substrates. Shows highest activity toward di- unsaturated diacylglycerol species as lipid substrates. The CDP- ethanolamine pathway may play a role in maintaining the proper PE spec [...] (391 aa)
         
  0.980
SPO14
Phospholipase D; catalyzes the hydrolysis of phosphatidylcholine, producing choline and phosphatidic acid; involved in Sec14p-independent secretion; required for meiosis and spore formation; differently regulated in secretion and meiosis; participat /.../transcription initiation and/or early elongation of specific genes; interacts with "foot domain" of RNA polymerase II; deletion results in abnormal CTD-Ser5 phosphorylation of RNA polymerase II at specific promoter regions; Required for meiosis and spore formation. Seems to be involved in the coordinate induction of late meiotic events [...] (1683 aa)
       
  0.979
OPI3
Phospholipid methyltransferase (methylene-fatty-acyl-phospholipid synthase), catalyzes the last two steps in phosphatidylcholine biosynthesis; Catalyzes three sequential methylation reactions of phosphatidylethanolamine (PE) by AdoMet, thereby producing phosphatidylcholine (PC) (206 aa)
     
 
  0.941
PSD2
Phosphatidylserine decarboxylase of the Golgi and vacuolar membranes, converts phosphatidylserine to phosphatidylethanolamine; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer). Plays a central role in phospholipid metabolism and in the interorganelle trafficking of phosphatidylserine (PubMed-7890740, PubMed-7890739, PubMed-24366873). Phosphatidylethanolamine produced by PSD2 is insufficient to completely provide the PtdEtn pool required by mitochondria under respiratory conditions (PubMed-11294902). PSD2 is also involved in the PtdSer transp [...] (1138 aa)

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)

CRD1
Cardiolipin synthase; produces cardiolipin, which is a phospholipid of the mitochondrial inner membrane that is required for normal mitochondrial membrane potential and function; also required for normal vacuolar ion homeostasis; Catalyzes the synthesis of cardiolipin (CL) (diphosphatidylglycerol) by specifically transferring a phosphatidyl group from CDP-diacylglycerol to phosphatidylglycerol (PG). CL is a key phospholipid in mitochondrial membranes and plays important roles in maintaining the functional integrity and dynamics of mitochondria under both optimal and stress conditions (283 aa)
