RUNX1T1 and coinfection: To confirm which step of the virus life cycle was inhibited by ETO and rescued by SIV VLP Q76A, we infected MDM with HIV‐1 BaL with and without co‐infection with SIV VLP Q76A and measured infection (Fig 3C), late RT products (Fig 3D), 2LTR circles (Fig 3E) and integration products (Fig 3F).
