The development of the E3L polyclonal antibody follows a well-defined procedure. It initiates with the repeated immunization of a rabbit using recombinant vaccinia virus E3 protein (1-190aa) until an optimal antibody titer is reached. Subsequently, the rabbit's blood is collected, and the antibodies are purified from the serum using protein A/G. The functionality of the resulting E3L antibody is thoroughly assessed through ELISA and WB applications, confirming its specific reactivity with the vaccinia virus E3 protein.

The E3L gene encodes the vaccinia virus E3 protein, a double-stranded RNA (dsRNA)-binding protein that inhibits the activation of interferon (IFN)-induced dsRNA-dependent protein kinase (PKR) and acts as an inhibitor of the IFN-induced 2-5A-synthetase enzyme. In addition to IFN-induced antiviral activity, E3 is also a key host-range protein, which suppresses the innate antiviral immune response of the infected cells.

Target Background

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. Blocks also the phosphorylation and subsequent activation of IRF3 and IRF7 kinases that are required for interferon-alpha gene expression. Inhibits NF-kappa-B activation and the ubiquitin-like protein ISG15, which is an early antiviral protein. The binding with host ISG15 subsequently blocks host ISGylation. Inhibits ZBP1-dependent necroptosis via interaction with host ZBP1.
