STRINGSTRING
GCR2 protein (Saccharomyces cerevisiae) - STRING interaction network
"GCR2" - Transcriptional activator of genes involved in glycolysis 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

GCR2Transcriptional activator of genes involved in glycolysis; interacts and functions with the DNA-binding protein Gcr1p; Transcriptional activator required for the expression of glycolytic genes. Enhances the CT box-dependent transcriptional activation of a RAP1-GCR1 complex. Required for GCR1 phosphorylation (534 aa)    
Predicted Functional Partners:
GCR1
Transcriptional activator of genes involved in glycolysis; DNA-binding protein that interacts and functions with the transcriptional activator Gcr2p; Transcriptional activator required for the expression of glycolytic and ribosomal genes. Forms a transcriptional activation complex with RAP1, RAP1 providing the specific DNA-binding function and GCR1 providing the activation function. Can also bind itself to DNA to a core 5’-CTTCC-3’ sequence (CT box). CT box- binding is not essential, but enhances the activation function of the RAP1-GCR1 complex in promoters that contain both DNA signal [...] (785 aa)

RAP1
DNA-binding protein involved in either activation or repression of transcription, depending on binding site context; also binds telomere sequences and plays a role in telomeric position effect (silencing) and telomere structure; Essential regulatory protein in yeast whose DNA-binding sites are found at three types of chromosomal elements- promoters, silencers, and telomeres. RAP1 is also involved in the regulation of telomere structure, where its binding sites are found within the terminal poly[C(1-3)A] sequences. The opposite regulatory functions of RAP1 are not intrinsic to its bindi [...] (827 aa)

TYE7
Serine-rich protein that contains a basic-helix-loop-helix (bHLH) DNA binding motif; binds E-boxes of glycolytic genes and contributes to their activation; may function as a transcriptional activator in Ty1-mediated gene expression; Transcriptional activator of glycolytic gene expression, such as enolase genes (ENO1 and ENO2), glyceraldehyde-3-phosphate dehydrogenase gene (TDH), phosphoglycerate kinase (PGK1), phosphoglycerate mutase (PGM1), pyruvate kinase (PYK1) and triosephosphate isomerase (TPI1) genes. Binds DNA on E-box motifs- 5’-CANNTG-3’ (291 aa)
       
 
  0.684
STB2
Protein that interacts with Sin3p in a two-hybrid assay and is part of a large protein complex with Sin3p and Stb1p (850 aa)
       
 
  0.633
MIG1
Transcription factor involved in glucose repression; sequence specific DNA binding protein containing two Cys2His2 zinc finger motifs; regulated by the SNF1 kinase and the GLC7 phosphatase; Involved in glucose repression of the SUC, GAL and MAL genes as well as of the CAT8 gene. Binds to two sites in the upstream region of SUC2 (504 aa)
       
 
  0.525
MRK1
Glycogen synthase kinase 3 (GSK-3) homolog; one of four GSK-3 homologs in S. cerevisiae that function to activate Msn2p-dependent transcription of stress responsive genes and that function in protein degradation (501 aa)
       
      0.507
RTG3
bHLH/Zip transcription factor for retrograde (RTG) and TOR pathways; forms a complex with another bHLH/Zip protein, Rtg1p, to activate the pathways; target of Hog1p; Transcription factor that regulates CIT2 gene expression. Binds to two identical sites oriented as inverted repeats 28 bp apart in a regulatory upstream activation sequence element (UASR) in the CIT2 promoter. The core binding site is 5’- GGTCAC-3’ (486 aa)

HAP4
Subunit of the heme-activated, glucose-repressed Hap2p/3p/4p/5p CCAAT-binding complex, a transcriptional activator and global regulator of respiratory gene expression; provides the principal activation function of the complex; Acts a component of the CCAT-binding factor, which is a transcriptional activator and binds to the upstream activation site (UAS2) of the CYC1 gene and other genes involved in mitochondrial electron transport and activates their expression. Recognizes the sequence 5’-CCAAT-3’. HAP4 encodes a regulatory subunit of the DNA-bound complex and seems to provide the pri [...] (554 aa)

KCS1
Inositol hexakisphosphate (IP6) and inositol heptakisphosphate (IP7) kinase; generation of high energy inositol pyrophosphates by Kcs1p is required for many processes such as vacuolar biogenesis, stress response and telomere maintenance; Converts inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). Involved in phosphate regulation and polyphosphate accumulation. Required for resistance to salt stress, cell wall integrity, vacuole morphogenesis, and telomere maintenance (1050 aa)

NUP53
Subunit of the nuclear pore complex (NPC), interacts with karyopherin Kap121p or with Nup170p via overlapping regions of Nup53p, involved in activation of the spindle checkpoint mediated by the Mad1p-Mad2p complex; Functions as a component of the nuclear pore complex (NPC). NPC components, collectively referred to as nucleoporins (NUPs), can play the role of both NPC structural components and of docking or interaction partners for transiently associated nuclear transport factors.
