Recombinant Vaccinia virus Serine proteinase inhibitor 3(SPI-3)

Product Type Recombinant Protein
Uniprot No. P18384
Species Vaccinia virus (strain Western Reserve) (VACV) (Vaccinia virus (strain WR))
Gene Names SPI-3
Protein Names Recommended name: Serine proteinase inhibitor 3
Storage The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Function Prevents cell to cell fusion via its interaction with A56 protein. The A56-K2 complex associates with components of the entry fusion complex (EFC) presumably to avoid superinfection and syncytium formation.
Subcellular Location Virion membrane, Peripheral membrane protein, Host cell membrane, Peripheral membrane protein, Extracellular side
Protein Families Serpin family, Poxviruses subfamily
