Structural polyprotein - P08563 (POLS_RUBVM)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P08563: 8
Capsid protein: Capsid protein interacts with genomic RNA and assembles into icosahedric core particles 65-70 nm in diameter (PubMed:28575072). The resulting nucleocapsid eventually associates with the cytoplasmic domain of E2 at the cell membrane, leading to budding and formation of mature virions from host Golgi membranes (PubMed:28575072). Phosphorylation negatively regulates RNA-binding activity, possibly delaying virion assembly during the viral replication phase. Capsid protein dimerizes and becomes disulfide-linked in the virion (PubMed:24282305). Modulates genomic RNA replication. Modulates subgenomic RNA synthesis by interacting with human C1QBP/SF2P32 (PubMed:10823864). Induces both perinuclear clustering of mitochondria and the formation of electron-dense intermitochondrial plaques, both hallmarks of rubella virus infected cells (PubMed:16051872). Induces apoptosis when expressed in transfected cells (PubMed:11017784). UniProt

Subunit Structure
Capsid protein: Homodimer; further assembles into homooligomer (PubMed:8614992, PubMed:24282305). Interacts with human C1QBP (PubMed:10823864, PubMed:16051872). Capsid protein: Interacts (via N-terminus) with protease/methyltransferase p150 (PubMed:25056903). Spike glycoprotein E1: Heterodimer with spike glycoprotein E2 (PubMed:9765418). Spike glycoprotein E2: Heterodimer with spike glycoprotein E1 (PubMed:9765418). UniProt
Capsid protein: The capsid protein is probably attached to the viral membrane through the E2 signal peptide (PubMed:2214022). This domain is also required for the localization of the capsid protein to the juxtanuclear region and subsequent virus assembly at the Golgi complex (PubMed:11160697). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
