Host proteins CPSF6, NUP153, and SEC24C are vital for HIV-1 infection. They bind to the viral capsid protein and contribute to shuttling of virions through the cytoplasm (SEC24C), import into the nucleus (NUP153 and CPSF6) and subsequent trafficking to preferred integration sites (CPSF6). Here, Wei et al. combine structural, biochemical and virological assays to emphasize the importance of prion-like low complexity domains surrounding short phenylalanine-glycine regions in binding and increasing the avidity when interacting with viral capsid.
