STRINGSTRING
UPF3 protein (Saccharomyces cerevisiae) - STRING interaction network
"UPF3" - Component of the nonsense-mediated mRNA decay 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

UPF3Component of the nonsense-mediated mRNA decay (NMD) pathway, along with Nam7p and Nmd2p; involved in decay of mRNA containing nonsense codons; involved in telomere maintenance; Involved in nonsense-mediated decay of mRNAs containing premature stop codons (387 aa)    
Predicted Functional Partners:
NMD2
Protein involved in the nonsense-mediated mRNA decay (NMD) pathway; interacts with Nam7p and Upf3p; involved in telomere maintenance; Involved in nonsense-mediated decay of mRNAs containing premature stop codons. It interacts, via its C-terminus, with NAM7/UPF1. Could be involved in determining the efficiency of translational termination or reinitiation or factors involved in the initial assembly of an initiation- and termination-competent mRNP (1089 aa)
     
  0.999
NAM7
ATP-dependent RNA helicase of the SFI superfamily involved in nonsense mediated mRNA decay; required for efficient translation termination at nonsense codons and targeting of NMD substrates to P-bodies; involved in telomere maintenance; Probable helicase involved in mitochondrial functions. Required for rapid turnover of mRNAs containing a premature translational termination codon (971 aa)
     
  0.999
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)
     
 
  0.984
TIF1
Translation initiation factor eIF4A, identical to Tif2p; DEA(D/H)-box RNA helicase that couples ATPase activity to RNA binding and unwinding; forms a dumbbell structure of two compact domains connected by a linker; interacts with eIF4G; ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5’-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning fo [...] (395 aa)
       
 
  0.928
SUP45
Polypeptide release factor (eRF1) in translation termination; mutant form acts as a recessive omnipotent suppressor; methylated by Mtq2p-Trm112p in ternary complex eRF1-eRF3-GTP; mutation of methylation site confers resistance to zymocin; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA (437 aa)
     
 
  0.907
TIF2
Translation initiation factor eIF4A, identical to Tif1p; DEA(D/H)-box RNA helicase that couples ATPase activity to RNA binding and unwinding; forms a dumbbell structure of two compact domains connected by a linker; interacts with eIF4G (395 aa)

MEX67
Poly(A)RNA binding protein involved in nuclear mRNA export, component of the nuclear pore; ortholog of human TAP; Involved in the export of mRNA from the nucleus to the cytoplasm (599 aa)
     
  0.859
DCP1
Subunit of the Dcp1p-Dcp2p decapping enzyme complex, which removes the 5’ cap structure from mRNAs prior to their degradation; enhances the activity of catalytic subunit Dcp2p; regulated by DEAD box protein Dhh1p; Component of the decapping complex necessary for the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay. Removes the 7-methyl guanine cap structure from mRNA molecules, yielding a 5’-phosphorylated mRNA fragment and 7m-GDP. Decapping is the major pathway of mRNA degradation in yeast. It occurs through deadenylation, decapping and subsequent [...] (231 aa)

XRN1
Evolutionarily-conserved 5’-3’ exonuclease component of cytoplasmic processing (P) bodies involved in mRNA decay; plays a role in microtubule-mediated processes, filamentous growth, ribosomal RNA maturation, and telomere maintenance; Multifunctional protein that exhibits several independent functions at different levels of the cellular processes. 5’-3’ exonuclease component of the nonsense-mediated mRNA decay (NMD) which is a highly conserved mRNA degradation pathway, an RNA surveillance system whose role is to identify and rid cells of mRNA with premature termination codons and thus p [...] (1528 aa)

FAL1
Nucleolar protein required for maturation of 18S rRNA, member of the eIF4A subfamily of DEAD-box ATP-dependent RNA helicases; ATP-dependent RNA helicase involved in 40S ribosomal subunit biogenesis. Required for the processing and cleavage of 35S pre-rRNA at sites A0, A1, and A2, leading to mature 18S rRNA (399 aa)
