STRINGSTRING
MET4 protein (Saccharomyces cerevisiae) - STRING interaction network
"MET4" - Leucine-zipper transcriptional activator, responsible for the regulation of the sulfur amino acid pathway, requires different combinations of the auxiliary factors Cbf1p, Met28p, Met31p and Met32p 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

MET4Leucine-zipper transcriptional activator, responsible for the regulation of the sulfur amino acid pathway, requires different combinations of the auxiliary factors Cbf1p, Met28p, Met31p and Met32p; Positive trans-acting factor capable of stimulating the transcription of the MET genes from the methionine biosynthetic pathway. MET4, MET28 and CBF1 are required for full induction of MET25 and MET16 gene transcription. MET4 controls as well the derepression of MET6. Required for the transcription of genes necessary for sulfur amino acid biosynthesis. Involved in the transcription activatio [...] (672 aa)    
Predicted Functional Partners:
MET28
bZIP transcriptional activator in the Cbf1p-Met4p-Met28p complex; participates in the regulation of sulfur metabolism; Acts as an accessory factor in the activation of sulfur amino acids metabolism genes. Possesses no intrinsic transcription activation abilities. Binds to the MET16 promoter as a complex with MET4 and CBF1. Enhances the DNA-binding activity of CBF1 (187 aa)
       
  0.998
CBF1
Dual function helix-loop-helix protein; binds the motif CACRTG present at several sites including MET gene promoters and centromere DNA element I (CDEI); affects nucleosome positioning at this motif; associates with other transcription factors such /.../4p and Isw1p to mediate transcriptional activation or repression; associates with kinetochore proteins and required for efficient chromosome segregation; Required for chromosome stability and methionine prototrophy. It is involved in chromosomal segregation. Binds to a highly conserved DNA sequence (5’-RTCACRTG-3’), called CDEI, found [...] (351 aa)
       
  0.998
MET30
F-box protein containing five copies of the WD40 motif, controls cell cycle function, sulfur metabolism, and methionine biosynthesis as part of the ubiquitin ligase complex; interacts with and regulates Met4p, localizes within the nucleus; Negatively regulates sulfur amino acids biosynthesis genes expression. Controls cell cycle function (being required for the G1/S transition and M-phase but not the S-phase), sulfur metabolism, and methionine biosynthesis as part of the E3 ubiquitin ligase complex SCF(Met30). Required for the efficient binding of CDC45 and MCM proteins to origins of r [...] (640 aa)
       
 
  0.979
MET31
Zinc-finger DNA-binding protein, involved in transcriptional regulation of the methionine biosynthetic genes, similar to Met32p; Auxiliary transcriptional regulator of sulfur amino acid metabolism. Involved in the transcriptional activation of MET28 (177 aa)
       
 
  0.975
MET32
Zinc-finger DNA-binding protein, involved in transcriptional regulation of the methionine biosynthetic genes, similar to Met31p; Auxiliary transcriptional regulator of sulfur amino acid metabolism. Involved in the transcriptional activation of MET28 (191 aa)
       
 
  0.966
CDC34
Ubiquitin-conjugating enzyme (E2) and catalytic subunit of SCF ubiquitin-protein ligase complex (together with Skp1p, Rbx1p, Cdc53p, and an F-box protein) that regulates cell cycle progression by targeting key substrates for degradation; Catalyzes the covalent attachment of ubiquitin to other proteins. Capable, in vitro, to ubiquitinate histone H2A (295 aa)
       
 
  0.935
MET16
3’-phosphoadenylsulfate reductase, reduces 3’-phosphoadenylyl sulfate to adenosine-3’,5’-bisphosphate and free sulfite using reduced thioredoxin as cosubstrate, involved in sulfate assimilation and methionine metabolism; The NADP dependent reduction of PAPS into sulfite involves thioredoxin which probably plays the role of a thiol carrier (261 aa)
           
  0.895
SKP1
Evolutionarily conserved kinetochore protein that is part of multiple protein complexes, including the SCF ubiquitin ligase complex, the CBF3 complex that binds centromeric DNA, and the RAVE complex that regulates assembly of the V-ATPase; Essential component of the E3 ubiquitin ligase complex SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins like phosphorylated SIC1. Participates in the attachment of chromosomes to the spindle. Acts as a regulatory component of the centromere DNA-binding [...] (194 aa)
       
 
  0.864
CDC53
Cullin, structural protein of SCF complexes (which also contain Skp1p, Cdc34p, Hrt1p and an F-box protein) involved in ubiquitination; SCF promotes the G1-S transition by targeting G1 cyclins and the Cln-CDK inhibitor Sic1p for degradation; Core component of multiple cullin-RING-based SCF (SKP1- CUL1-F-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins.
