Vaccinia virus with the E3L gene deleted was able to replicate in RK-13 but not HeLa cells. This host range phenotype could be complemented by an E3L gene expressed transiently from a plasmid. Analysis of mutants of E3L indicates that the ability to complement deletion of E3L correlates with the ability of mutated proteins to bind double-stranded RNA but not with their ability to migrate to the nucleus.
