STRINGSTRING
FPS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FPS1" - Plasma membrane channel, member of major intrinsic protein 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

FPS1Plasma membrane channel, member of major intrinsic protein (MIP) family; involved in efflux of glycerol and in uptake of acetic acid and the trivalent metalloids arsenite and antimonite; phosphorylated by Hog1p MAPK under acetate stress; Channel protein for glycerol. Has a role in both glycerol influx and efflux. Plays a role in osmoregulation- under osmotic stress the channel is apparently closed to allow accumulation of glycerol in the cell under hyperosmotic conditions (669 aa)    
Predicted Functional Partners:
HOG1
Mitogen-activated protein kinase involved in osmoregulation; acts via three independent osmosensors; mitophagy-specific regulator; mediates the recruitment and activation of RNA Pol II at Hot1p-dependent promoters; localization regulated by Ptp2p an /.../p; Mitogen-activated protein kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment. Controls osmotic regulation of transcription via the stress response element (STRE) in promoters of target genes. Upon osmotic shock, associates with the SKO1-SSN6-TUP1 complex, [...] (435 aa)

GUT1
Glycerol kinase, converts glycerol to glycerol-3-phosphate; glucose repression of expression is mediated by Adr1p and Ino2p-Ino4p; derepression of expression on non-fermentable carbon sources is mediated by Opi1p and Rsf1p (709 aa)
   
 
  0.951
GLT1
NAD(+)-dependent glutamate synthase (GOGAT), synthesizes glutamate from glutamine and alpha-ketoglutarate; with Gln1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source; Forms L-glutamate from L-glutamine and 2-oxoglutarate. Represents an alternative pathway to L-glutamate dehydrogenase for the biosynthesis of L-glutamate. Participates with glutamine synthetase in ammonia assimilation processes. The enzyme is specific for NADH, L-glutamine and 2-oxoglutarate (2145 aa)
     
 
  0.939
ERG20
Farnesyl pyrophosphate synthetase, has both dimethylallyltranstransferase and geranyltranstransferase activities; catalyzes the formation of C15 farnesyl pyrophosphate units for isoprenoid and sterol biosynthesis; Catalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate (352 aa)
       
 
  0.916
SLN1
Histidine kinase osmosensor that regulates a MAP kinase cascade; transmembrane protein with an intracellular kinase domain that signals to Ypd1p and Ssk1p, thereby forming a phosphorelay system similar to bacterial two-component regulators; Histidine kinase that acts as a osmosensor at the plasma membrane. Part of the bifurcated SLN1-YPD1-SKN7/SSK1 two-component regulatory system, which controls activity of the HOG1 pathway and gene expression in response to changes in the osmolarity of the extracellular environment. Under normal osmotic conditions, the histidine kinase autophosphoryla [...] (1220 aa)
       
 
  0.884
SSK2
MAP kinase kinase kinase of the HOG1 mitogen-activated signaling pathway; interacts with Ssk1p, leading to autophosphorylation and activation of Ssk2p which phosphorylates Pbs2p; also mediates actin cytoskeleton recovery from osmotic stress; Kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment. Activates the PBS2 MAP kinase kinase by phosphorylation (1579 aa)
       
 
  0.843
STL1
Glycerol proton symporter of the plasma membrane, subject to glucose-induced inactivation, strongly but transiently induced when cells are subjected to osmotic shock (569 aa)
       
 
  0.842
GUT2
Mitochondrial glycerol-3-phosphate dehydrogenase; expression is repressed by both glucose and cAMP and derepressed by non-fermentable carbon sources in a Snf1p, Rsf1p, Hap2/3/4/5 complex dependent manner (649 aa)
   
   
  0.840
PPZ1
Serine/threonine protein phosphatase Z, isoform of Ppz2p; involved in regulation of potassium transport, which affects osmotic stability, cell cycle progression, and halotolerance; Essential for the maintenance of cell size and integrity in response to osmotic stress (692 aa)
       
 
  0.833
ASK10
Component of RNA polymerase II holoenzyme, phosphorylated in response to oxidative stress; has a role in destruction of Ssn8p; proposed to function in activation of the glycerol channel Fps1p; paralogous to Rgc1p; Positive regulator of FPS1 glycerol channel required for the glycerol efflux. As a component of the RNA polymerase II holoenzyme, is required for SSN8 destruction in response to oxidative stress but not heat shock. Required for cell survival in response to heat shock independent of SSN8 (1146 aa)
