E3 ubiquitin-protein ligase listerin - Q04781 (LTN1_YEAST)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q04781: 2
 
Function
E3 ubiquitin-protein ligase component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesized nascent chains for proteasomal degradation (PubMed:23178123). Mediates ubiquitination of proteins derived from mRNAs lacking stop codons (non-stop proteins) and other translation arrest products induced by poly-lysine sequences and tandem rare codons. Ubiquitination leads to CDC48 recruitment for extraction and degradation of the incomplete translation product (PubMed:20835226, PubMed:23825054, PubMed:24261871). May indirectly play a role in chromatin function and transcription (PubMed:17283062). UniProt

Subunit Structure
Component of the ribosome quality control complex (RQC), composed of the E3 ubiquitin ligase RKR1/LTN1, RQC1 and RQC2, as well as CDC48 and its ubiquitin-binding cofactors. RQC forms a stable complex with 60S ribosomal subunits (PubMed:23178123, PubMed:23479637, PubMed:25349383). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
