STRINGSTRING
MKS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MKS1" - Pleiotropic negative transcriptional regulator involved in Ras-CAMP and lysine biosynthetic pathways and nitrogen regulation 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

MKS1Pleiotropic negative transcriptional regulator involved in Ras-CAMP and lysine biosynthetic pathways and nitrogen regulation; involved in retrograde (RTG) mitochondria-to-nucleus signaling; Negative regulator of Ras-cAMP pathway. Involved in transcriptional regulation of galactose-inducible genes (584 aa)    
Predicted Functional Partners:
RTG2
Sensor of mitochondrial dysfunction; regulates the subcellular location of Rtg1p and Rtg3p, transcriptional activators of the retrograde (RTG) and TOR pathways; Rtg2p is inhibited by the phosphorylated form of Mks1p; Required for a novel path of interorganelle communication between mitochondria, peroxisomes and the nucleus, thereby maintaining a functional metabolic interaction between the tricarboxylic acid and glyoxylate cycles. In particular, required for the retrograde expression of the peroxisomal isoform of citrate synthase, CIT2 (588 aa)
       
 
  0.919
BMH1
14-3-3 protein, major isoform; controls proteome at post-transcriptional level, binds proteins and DNA, involved in regulation of many processes including exocytosis, vesicle transport, Ras/MAPK signaling, and rapamycin-sensitive signaling; Involved in growth regulation (267 aa)
       
 
  0.887
GLN3
Transcriptional activator of genes regulated by nitrogen catabolite repression (NCR), localization and activity regulated by quality of nitrogen source; Positive nitrogen regulatory protein. Required for the activation of transcription of a number of genes (including the allantoin pathway genes) in response to the replacement of glutamine by glutamate as source of nitrogen. Binds the nitrogen upstream activation sequence of GLN1, the gene encoding glutamine synthetase. URE2 may catalytically inactivate GLN3 in response to an increase in the intracellular concentration of glutamine (730 aa)
       
 
  0.789
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)
       
 
  0.777
RTG1
Transcription factor (bHLH) involved in interorganelle communication between mitochondria, peroxisomes, and nucleus; Required for a novel path of interorganelle communication between mitochondria, peroxisomes and the nucleus, thereby maintaining a functional metabolic interaction between the tricarboxylic acid and glyoxylate cycles. 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’ (177 aa)
       
 
  0.775
KOG1
Subunit of TORC1, a rapamycin-sensitive complex involved in growth control that contains Tor1p or Tor2p, Lst8p and Tco89p; contains four HEAT repeats and seven WD-40 repeats; may act as a scaffold protein to couple TOR and its effectors; Component of TORC1, which regulates multiple cellular processes to control cell growth in response to environmental signals. Nutrient limitation and environmental stress signals cause inactivation of TORC1. Active TORC1 positively controls ribosome biogenesis via control of rRNA, ribosomal protein and tRNA gene expression, and rRNA processing. TORC1 po [...] (1557 aa)
       
 
  0.771
URE2
Nitrogen catabolite repression transcriptional regulator that acts by inhibition of GLN3 transcription in good nitrogen source; has glutathione peroxidase activity and can mutate to acquire GST activity; altered form creates [URE3] prion; Plays an important role in nitrogen catabolite repression. Down-regulates the expression of many genes involved in nitrogen utilization by inhibiting the GATA transcriptional activators GLN3 and GAT1. Under good nitrogen conditions, binds to the phosphorylated forms of GLN3 and GAT1 and sequesters them in the cytoplasm, preventing transcription of gen [...] (354 aa)

GRR1
F-box protein component of the SCF ubiquitin-ligase complex; involved in carbon catabolite repression, glucose-dependent divalent cation transport, high-affinity glucose transport, morphogenesis, and sulfite detoxification; Substrate recognition component of a SCF (SKP1-CUL1-F- box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and directs ubiquitination of phosphorylated CLN1, CLN2 and GIC2. Probably constitutes the primary response element required for the generation or interpretatio [...] (1151 aa)

YNL208W
Protein of unknown function; may interact with ribosomes, based on co-purification experiments; authentic, non-tagged protein is detected in purified mitochondria in high-throughput studies; potential orthologs found in other fungi (199 aa)
       
      0.699
HTA1
Histone H2A, core histone protein required for chromatin assembly and chromosome function; one of two nearly identical subtypes (see also HTA2); DNA damage-dependent phosphorylation by Mec1p facilitates DNA repair; acetylated by Nat4p; Core component of nucleosome which plays a central role in DNA double strand break (DSB) repair. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. D [...] (132 aa)
