STRINGSTRING
GAL3 protein (Saccharomyces cerevisiae) - STRING interaction network
"GAL3" - Transcriptional regulator involved in activation of the GAL genes in response to galactose 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

GAL3Transcriptional regulator involved in activation of the GAL genes in response to galactose; forms a complex with Gal80p to relieve Gal80p inhibition of Gal4p; binds galactose and ATP but does not have galactokinase activity; The GAL3 regulatory function is required for rapid induction of the galactose system. At normal induction, galactose in the presence of the GAL3 protein may lead to the induction of the GAL genes, including GAL1. Then the galactokinase protein (GAL1) in the presence of galactose may reinforce the induction leading to a higher expression level. Upon depletion of gal [...] (520 aa)    
Predicted Functional Partners:
GAL10
UDP-glucose-4-epimerase, catalyzes the interconversion of UDP-galactose and UDP-D-glucose in galactose metabolism; also catalyzes the conversion of alpha-D-glucose or alpha-D-galactose to their beta-anomers; Mutarotase converts alpha-aldose to the beta-anomer. It is active on D-glucose, L-arabinose, D-xylose, D-galactose, maltose and lactose (By similarity) (699 aa)
   
  0.999
GAL7
Galactose-1-phosphate uridyl transferase, synthesizes glucose-1-phosphate and UDP-galactose from UDP-D-glucose and alpha-D-galactose-1-phosphate in the second step of galactose catabolism (366 aa)
 
  0.999
GAL80
Transcriptional regulator involved in the repression of GAL genes in the absence of galactose; inhibits transcriptional activation by Gal4p; inhibition relieved by Gal3p or Gal1p binding; This protein is a negative regulator for the gene expression of the lactose/galactose metabolic genes. It binds to GAL4 and so blocks transcriptional activation by it, in the absence of an inducing sugar (435 aa)
   
 
  0.996
GAL4
DNA-binding transcription factor required for activating GAL genes; responds to galactose; repressed by Gal80p and activated by Gal3p; This protein is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which code for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5’-CGGRNNRCYNYNCNCCG-3’) the upstream activating sequence (UAS-G) of these genes (881 aa)
       
 
  0.975
GAL1
Galactokinase, phosphorylates alpha-D-galactose to alpha-D-galactose-1-phosphate in the first step of galactose catabolism; expression regulated by Gal4p (528 aa)
     
0.935
YNR071C
Putative aldose 1-epimerase (342 aa)
 
  0.918
YHR210C
Putative aldose 1-epimerase superfamily protein; non-essential gene; highly expressed under anaeorbic conditions (341 aa)
   
  0.913
PGM2
Phosphoglucomutase, catalyzes the conversion from glucose-1-phosphate to glucose-6-phosphate, which is a key step in hexose metabolism; functions as the acceptor for a Glc-phosphotransferase; Major phosphoglucomutase isozyme that catalyzes the reversible interconversion of glucose 1-phosphate and glucose 6- phosphate (PubMed-5784209). Constitutes about 80-90% of the phosphoglucomutase activity in the cell (PubMed-14264884, PubMed-5231755). Key enzyme in hexose metabolism. The forward reaction is an essential step in the energy metabolism of galactose since the product of the galactose [...] (569 aa)
     
 
  0.845
GAL2
Galactose permease, required for utilization of galactose; also able to transport glucose; GAL2 is a facilitated diffusion transporter required for both the high-affinity galactokinase-dependent and low-affinity galactokinase-independent galactose transport processes (574 aa)
   
   
  0.824
CKS1
Cyclin-dependent protein kinase regulatory subunit and adaptor; modulates proteolysis of M-phase targets through interactions with the proteasome; role in transcriptional regulation, recruiting proteasomal subunits to target gene promoters; Binds to the catalytic subunit of the cyclin dependent kinase (CDC28) and is essential for its biological function (150 aa)
