STRINGSTRING
PAH1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PAH1" - Mg2+-dependent phosphatidate 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

PAH1Mg<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)    
Predicted Functional Partners:
DPP1
Diacylglycerol pyrophosphate (DGPP) phosphatase, zinc-regulated vacuolar membrane-associated lipid phosphatase, dephosphorylates DGPP to phosphatidate (PA) and Pi, then PA to diacylglycerol; involved in lipid signaling and cell metabolism; Catalyzes the dephosphorylation of diacylglycerol diphosphate (DGPP) to phosphatidate (PA) and the subsequent dephosphorylation of PA to diacylglycerol (DAG). Together with LPP1, regulates intracellular DGPP and PA levels, which are phospholipid molecules believed to play a signaling role in stress response. Can also use lysophosphatidic acid (LPA) a [...] (289 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)

DGA1
Diacylglycerol acyltransferase, catalyzes the terminal step of triacylglycerol (TAG) formation, acylates diacylglycerol using acyl-CoA as an acyl donor, localized to lipid particles; Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. Required for storage lipid synthesis. May be involved in lipid particle synthesis from the endoplasmic reticulum and ergosterol biosynthesis. Also has monoacylglycerol acyltransferase (MGAT) activity, catalyzing the acyl-CoA-dependent esterification of monoacylglycerol to di [...] (418 aa)

PKC1
Protein serine/threonine kinase essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC); Required for cell growth and for the G2->M transition of the cell division cycle. Mediates a protein kinase cascade; it activates BCK1 which itself activates MKK1/MKK2 (1151 aa)
     
  0.985
NEM1
Probable catalytic subunit of Nem1p-Spo7p phosphatase holoenzyme; regulates nuclear growth by controlling phospholipid biosynthesis, required for normal nuclear envelope morphology and sporulation; homolog of the human protein Dullard; Essential for the formation of a spherical nucleus and meiotic division. Catalytic component of the NEM1-SPO7 complex which acts as a phosphatase and dephosphorylates SMP2 (446 aa)

LRO1
Acyltransferase that catalyzes diacylglycerol esterification; one of several acyltransferases that contribute to triglyceride synthesis; putative homolog of human lecithin cholesterol acyltransferase; Triacylglycerol formation by an acyl-CoA independent pathway. The enzyme specifically transfers acyl groups from the sn-2 position of a phospholipid to diacylglycerol, thus forming an sn-1-lysophospholipid (661 aa)

CDC28
Catalytic subunit of the main cell cycle cyclin-dependent kinase (CDK); alternately associates with G1 cyclins (CLNs) and G2/M cyclins (CLBs) which direct the CDK to specific substrates; This protein is essential for the completion of the start, the controlling event, in the cell cycle. More than 200 substrates have been identified (298 aa)

LPP1
Lipid phosphate phosphatase, catalyzes Mg(2+)-independent dephosphorylation of phosphatidic acid (PA), lysophosphatidic acid, and diacylglycerol pyrophosphate; involved in control of the cellular levels of phosphatidylinositol and PA; Catalyzes the dephosphorylation of diacylglycerol phosphate (DGPP) to phosphatidate (PA) and the subsequent dephosphorylation of PA to diacylglycerol (DAG). Together with DPP1, regulates intracellular DGPP and PA levels which are phospholipid molecules believed to play a signaling role in stress response.
