Organization of arenavirus Z protein. All arenavirus Z proteins have G at position 2 (G2). Within the centrally located RING domain, all known arenavirus Z proteins possess an YxxL (or YxxL-like) motif. At their C-terminus, arenavirus Z proteins have different types of L domains. Lassa virus (LASV), lymphocytic choriomeningitis virus (LCMV), Mopeia virus (MOPV), Merino Walk virus (MWAV), Lujo virus (LUJV), Pichinde virus (PICV), Junin virus (JUNV), Machupo virus (MACV), Sabia virus (SABV), Tacaribe virus (TACV), Latino virus (LATV), Whitewater Arroyo virus (WWAV).
