UniProtKB - P0C2Q9 (VEMP_CVPIA)
Protein
Envelope small membrane protein
Gene
E
Organism
Porcine hemagglutinating encephalomyelitis virus (strain IAF-404) (HEV)
Status
Functioni
Plays a central role in virus morphogenesis and assembly. Acts as a viroporin and self-assembles in host membranes forming pentameric protein-lipid pores that allow ion transport. Also plays a role in the induction of apoptosis.UniRule annotation
