The host cell factor cyclophilin A (CypA) interacts with the HIV-1 capsid and regulates infectivity. Here the authors combine cryo-EM, solid-state NMR and all-atom MD simulations, identifying an interaction interface between CypA and the HIV capsid that stabilizes the viral capsid and regulates infectivity.
