We next investigated which stage of the VSV life cycle is affected by the loss of SLC30A1. Infection of HAP1 cells at MOI > 1 did not result in altered percentages of infected cells in SLC30A1 HAP1 knockout cells at early time points (Fig. 3a), indicating that loss of this transporter did not impair viral entry. Here, SLC30A1 is linked to infection.
