Research Abstract

Phagosome formation and subsequent maturation are complex sequences of events that involve actin cytoskeleton remodeling and membrane trafficking. In this study, we found that the Ras-related protein Rab35 is involved in the early stage of FcγR-mediated phagocytosis in macrophages. Our data indicate that Rab35 regulates actin-dependent phagosome formation by recruiting ACAP2, which might control actin remodeling and membrane traffic through ARF6.
