AB - Porcine Interferon (PoIFN) is a multifunctional secretory
protein produced by animal immune cells. IFN signaling activates host cells
resulting in anti-viral and -tumor immune regulation in addition to other biological
functions. Here, the coding region of PoIFN-• was amplified from porcine
genomic DNA by Polymerase Chain Reaction (PCR) and was cloned into the yeast
Pichia pastoris expression system. This resulted in high levels of gene
expression. Furthermore, expression of PoIFN-• was successfully detected
by Western-blot. The relative molecular weight of the product was 25 and 27
kDa. The recombinant PoIFN-• exhibited cross-species antiviral activity
in Marc-145 and BHK-21 mammalian cell lines. In summary, the results demonstrate
that recombinant PoIFN-• cloned into P. pastoris is expressed,
secreted and biologically active in mammalian cells.
