Salmonella effector SopD promotes plasma membrane scission by inhibiting Rab10

Abstract

Salmonella secretes the effector protein SopD into the host cell cytoplasm, leading to scission of the plasma membrane through unclear mechanisms. Here, Boddy et al. show that SopD binds to and inhibits the small GTPase Rab10, thus promoting removal of Rab10 and recruitment of dynamin-2 to drive plasma membrane scission.
