This product is a lacZ encoding oncolytic vaccinia virus, which is based on VACV-WR with E3L and K3L double deleted.Protein E3 plays a role in the inhibition of multiple cellular antiviral responses activated by dsRNA, such as inhibition of PKR activation, apoptosis, and IFN-mediated antiviral activities. Protein K3 acts as a pseudosubstrate for EIF2AK2/PKR kinase. Inhibits therefore eIF-2-alpha phosphorylation by host EIF2AK2/PKR kinase and prevents protein synthesis shutoff.The double deletion of E3L and K3L with oncolytic-rendered modifications could enhance an immune response to a poxvirus vaccine.This product can be used in oncolytic virotherapy research and vaccinie application.
