To test this and to identify CA residues that affect sensitivity to IP6 depletion, a panel of 37 HIV-1-GFP (HIV-1GFP) CA mutants was assayed for infection of WT or IPMK KO CEM cells previously transduced with a lentiviral vector expressing IPMK-Flag (IPMK KOIPMK-Flag) or, as a control, the corresponding empty vector (WTVector and IPMK KOVector, respectively) [24]. The gene discussed is IPMK; the disease is infection.
