    The poxvirus 2L protein binds tumor necrosis factor-alpha (TNFalpha) to inhibit host antiviral and immune responses. The 2.8-A 2L-TNFalpha structure reveals three symmetrically arranged 2L molecules per TNFalpha trimer. 2L resembles class I major histocompatibility complex (MHC) molecules but lacks a peptide-binding groove and beta2-microglobulin light chain. Overlap between the 2L and host TNF receptor-binding sites on TNFalpha rationalizes 2L inhibition of TNFalpha-TNF receptor interactions and prevention of TNFalpha-induced immune responses.
