ACTR2 and infection: The decrease in actin tails recruited by R. conorii in ScarWA-expressing cells is due to the overexpression of ScarWA sequestering Arp2/3, which further indicates that the Arp2/3 complex is hijacked during infection, as it is in Listeria-infected cells (Boujemaa-Paterski et al., 2001).
