Importantly, co-expressing KIF5 motorBFP-FRB (where blue fluorescent protein (BFP) is spliced in between the motor and FRB) in these cells along with adding the rapa linker (at infection or 5 hpi) almost completely restored large foci formation (Fig. 5e, bottom row; quantified in Fig. 5f). Here, TRERF1 is linked to infection.
