Genome polyprotein - Q5UB51 (POLG_DEN3I)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q5UB51: 4
Capsid protein C: Plays a role in virus budding by binding to the cell membrane and gathering the viral RNA into a nucleocapsid that forms the core of a mature virus particle. During virus entry, may induce genome penetration into the host cytoplasm after hemifusion induced by the surface proteins. Can migrate to the cell nucleus where it modulates host functions. Overcomes the anti-viral effects of host EXOC1 by sequestering and degrading the latter through the proteasome degradation pathway. UniProt

Subunit Structure
Capsid protein C: Homodimer. Interacts (via N-terminus) with host EXOC1 (via C-terminus); this interaction results in EXOC1 degradation through the proteasome degradation pathway. Protein prM: Forms heterodimers with envelope protein E in the endoplasmic reticulum and Golgi. Envelope protein E: Homodimer; in the endoplasmic reticulum and Golgi. Interacts with protein prM. Interacts with non-structural protein 1. Non-structural protein 1: Homodimer; Homohexamer when secreted. Interacts with envelope protein E. Non-structural protein 2A: Interacts (via N-terminus) with serine protease NS3. Non-structural protein 2B: Forms a heterodimer with serine protease NS3. May form homooligomers. Serine protease NS3: Forms a heterodimer with NS2B. Interacts with NS4B. Interacts with unphosphorylated RNA-directed RNA polymerase NS5; this interaction stimulates RNA-directed RNA polymerase NS5 guanylyltransferase activity. Non-structural protein 4A: Interacts with host MAVS; this interaction inhibits the synthesis of IFN-beta. Non-structural protein 4B: Interacts with serine protease NS3. RNA-directed RNA polymerase NS5: Homodimer. Interacts with host STAT2; this interaction inhibits the phosphorylation of the latter, and, when all viral proteins are present (polyprotein), targets STAT2 for degradation. Interacts with serine protease NS3. 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.
