PoELF4 is widely expressed in different tissues, especially the intestine and stomach.
PoELF4 is involved in the IFN-β signaling pathway in different porcine cells.
PoELF4 mutant lacking the serine/threonine rich domain still induces IFN-β expression.
PoELF4 significantly inhibits the replication of both PRV and PRRSV.
