TRIM2 and infection: We previously showed that the E3 ubiquitin ligase Tripartite Motif 2 (TRIM2) in complex with Signal Regulatory Protein Alpha/Tyrosine-protein phosphatase non-receptor type substrate 1 (SIRPA/SHPS1), a negative regulator of phagocytosis, limited New World arenavirus (NWA) entry but did not alter infection by other viruses, such as the Old World arenaviruses (OWA) Lassa fever virus and lymphocytic choriomeningitis virus (LCMV), or the rhabdovirus vesicular stomatitis virus (VSV) [4].
