STRINGSTRING
PES4 protein (Saccharomyces cerevisiae) - STRING interaction network
"PES4" - Poly(A) binding protein, suppressor of DNA polymerase epsilon mutation, similar to Mip6p 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

PES4Poly(A) binding protein, suppressor of DNA polymerase epsilon mutation, similar to Mip6p (611 aa)    
Predicted Functional Partners:
PBP1
Component of glucose deprivation induced stress granules, involved in P-body-dependent granule assembly; similar to human ataxin-2; interacts with Pab1p to regulate mRNA polyadenylation; interacts with Mkt1p to regulate HO translation; Appears to promote proper polyadenylation. In the absence of PBP1, the 3’termini of pre-mRNAs are properly cleaved but lack full-length poly(A) tails. May act to repress the ability of PAB1 to negatively regulate polyadenylation. Negative regulator of poly(A) nuclease (PAN) activity (722 aa)
     
 
  0.914
TEF2
Translational elongation factor EF-1 alpha; also encoded by TEF1; functions in the binding reaction of aminoacyl-tRNA (AA-tRNA) to ribosomes; may also have a role in tRNA re-export from the nucleus (458 aa)
     
 
  0.802
SUP35
Translation termination factor eRF3, has a role in mRNA deadenylation and decay; altered protein conformation creates the [PSI(+)] prion that alters translational fidelity and results in a nonsense suppressor phenotype; Involved in translation termination. Stimulates the activity of ERF1. Binds guanine nucleotides. Recruited by polyadenylate-binding protein PAB1 to poly(A)-tails of mRNAs. Interaction with PAB1 is also required for regulation of normal mRNA decay through translation termination-coupled poly(A) shortening (685 aa)
     
 
  0.801
TEF1
Translational elongation factor EF-1 alpha; also encoded by TEF2; functions in the binding reaction of aminoacyl-tRNA (AA-tRNA) to ribosomes; may also have a role in tRNA re-export from the nucleus; GTP-binding component of the eukaryotic elongation factor 1 complex (eEF1). In its active GTP-bound form, binds to and delivers aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis. In the presence of a correct codon-anticodon match between the aminoacyl-tRNA and the A-site codon of the ribosome-bound mRNA, the ribosome acts as a GTPase activator and the GTP is hydrolyzed. [...] (458 aa)
     
 
  0.799
BUD31
Component of the SF3b subcomplex of the U2 snRNP; diploid mutants display a random budding pattern instead of the wild-type bipolar pattern; Involved in pre-mRNA splicing. Important for bud site selection (157 aa)
       
      0.794
SKI7
Coupling protein that mediates interactions between the Ski complex and the cytoplasmic exosome during 3’-5’ RNA degradation; eRF3-like domain targets nonstop mRNA for degradation; null mutants have superkiller phenotype; Represses the expression of non-poly(A) mRNAs like L-A or M viruses and is therefore involved in antiviral system. Mediates interactions via its N-terminus between the exosome and the SKI complex which operate in the 3’-to-5’ mRNA-decay pathway. By interacting with NAM7, is also required for nonsense-mediated 3’-to-5’ mRNA-decay (NMD). May recognize a stalled 80S ribo [...] (747 aa)
     
 
  0.788
HBS1
GTPase with similarity to translation release factors; together with binding partner Dom34p, facilitates ribosomal subunit dissociation and peptidyl-tRNA release when translation is stalled; genetically implicated in mRNA no-go decay; Involved in protein translation. Together with DOM34, may function in recognizing stalled ribosomes and triggering endonucleolytic cleavage of the mRNA, a mechanism to release non- functional ribosomes and degrade damaged mRNAs (611 aa)
     
 
  0.788
CDC33
Cytoplasmic mRNA cap binding protein and translation initiation factor eIF4E; the eIF4E-cap complex is responsible for mediating cap-dependent mRNA translation via interactions with translation initiation factor eIF4G (Tif4631p or Tif4632p); Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures (213 aa)
       
  0.754
CDA1
Chitin deacetylase, together with Cda2p involved in the biosynthesis ascospore wall component, chitosan; required for proper rigidity of the ascospore wall; Hydrolyzes the N-acetamido groups of N-acetyl-D- glucosamine residues in chitin (301 aa)
     
   
  0.744
SWD2
Subunit of the COMPASS (Set1C) complex, which methylates histone H3 on lys 4 and is involved in telomeric silencing; subunit of CPF (cleavage and polyadenylation factor), a complex involved in RNAP II transcription termination; The COMPASS (Set1C) complex specifically mono-, di- and trimethylates histone H3 to form H3K4me1/2/3, which subsequently plays a role in telomere length maintenance and transcription elongation regulation (329 aa)
