Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P03305: 7
 
Function
Leader protease: Autocatalytically cleaves itself from the polyprotein at the L/VP0 junction. Cleaves also the host translation initiation factors EIF4G1 and EIF4G3, in order to shutoff the capped cellular mRNA transcription. Plays a role in counteracting host innate antiviral response using diverse mechanisms. Possesses a deubiquitinase activity acting on both 'Lys'-48 and 'Lys'-63-linked polyubiquitin chains. In turn, inhibits the ubiquitination and subsequent activation of key signaling molecules of type I IFN response such as host DDX58, TBK1, TRAF3 and TRAF6. Inhibits host NF-kappa-B activity by inducing a decrease in RELA mRNA levels. Cleaves a peptide bond in the C-terminus of host ISG15, resulting in the damaging of this mofidier that can no longer be attached to target proteins. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
