Small hydrophobic protein - P0DOE5 (SH_HRSVA)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Viroporin that forms a homopentameric ion channel displaying low ion selectivity (PubMed:18369195, PubMed:22621926, PubMed:25100835). May play a role in virus morphogenesis and pathogenicity at various stages of the viral life cycle. Accumulates at the membrane of the Golgi apparatus in infected cells and may facilitate virus release by modifying the secretory pathway (PubMed:15105532, PubMed:23229815). May enhance host membrane permeability and disrupt cellular ion homeostasis, which can be sensed as damage-associated molecular patterns/danger signals, triggering NLRP3 inflammasome activation and inflammatory immune response (PubMed:23229815). Also inhibits host TNFA-mediated signaling pathway and may delay apoptosis, allowing time for the virus to replicate (PubMed:17494063). UniProt

Subunit Structure
Homopentamer forming a funnel-like pore (PubMed:18369195, PubMed:22621926). Interacts with glycoprotein G; this interaction occurs on the surface of virion particles and infected cells (PubMed:18036342). Interacts with host BCAP31 (via C-terminus); this interaction is direct (PubMed:25854864). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
