STRINGSTRING
PLB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PLB1" - Phospholipase B 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

PLB1Phospholipase B (lysophospholipase) involved in lipid metabolism, required for deacylation of phosphatidylcholine and phosphatidylethanolamine but not phosphatidylinositol; Sequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol >> phosphatidylcholine > phosphatidylethanolamine (664 aa)    
Predicted Functional Partners:
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)
       
  0.964
GDE1
Glycerophosphocholine (GroPCho) phosphodiesterase; hydrolyzes GroPCho to choline and glycerolphosphate, for use as a phosphate source and as a precursor for phosphocholine synthesis; may interact with ribosomes; Glycerophosphocholine glycerophosphodiesterase responsible for the hydrolysis of intracellular glycerophosphocholine into glycerol-phosphate and choline. The choline is used for phosphatidyl-choline synthesis. Required for utilization of glycerophosphocholine as phosphate source (1223 aa)
     
 
  0.938
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)
         
  0.925
NTE1
Serine esterase, homolog of human neuropathy target esterase (NTE); Nte1p-mediated phosphatidylcholine turnover influences transcription factor Opi1p localization, affecting transcriptional regulation of phospholipid biosynthesis genes; Intracellular phospholipase B that catalyzes the double deacylation of phosphatidylcholine (PC) to glycerophosphocholine (GroPCho). Plays an important role in membrane lipid homeostasis. Responsible for the rapid PC turnover in response to inositol, elevated temperatures, or when choline is present in the growth medium (1679 aa)
         
  0.911
PLB2
Phospholipase B (lysophospholipase) involved in lipid metabolism; displays transacylase activity in vitro; overproduction confers resistance to lysophosphatidylcholine; Sequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol > phosphatidylcholine > phosphatidylethanolamine (706 aa)
       
0.888
PLB3
Phospholipase B (lysophospholipase) involved in phospholipid metabolism; hydrolyzes phosphatidylinositol and phosphatidylserine and displays transacylase activity in vitro; Sequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol. Does not cleave phosphatidylcholine, phosphatidylethanolamine, phosphatidic acid and phosphatidylinositol-bisphosphate (686 aa)
         
0.803
MON2
Peripheral membrane protein with a role in endocytosis and vacuole integrity, interacts with Arl1p and localizes to the endosome; member of the Sec7p family of proteins; Required for traffic between late Golgi and early endosomes. Required for endocytosis and maintenance of vacuolar structure (1636 aa)
       
 
  0.655
PCT1
Cholinephosphate cytidylyltransferase, also known as CTP-phosphocholine cytidylyltransferase, rate-determining enzyme of the CDP-choline pathway for phosphatidylcholine synthesis, inhibited by Sec14p, activated upon lipid-binding (424 aa)
       
 
  0.600
RNH1
Ribonuclease H1; able to bind double-stranded RNAs and RNA-DNA hybrids; associates with RNAse polymerase I; Endonuclease that specifically degrades the RNA of RNA- DNA hybrids (348 aa)
     
      0.511
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; G-3-P/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase (759 aa)
