Rab10 GTPase regulates ER dynamics and morphology.

Abstract excerpt

We have identified Rab10 as an ER-specific Rab GTPase that regulates ER structure and dynamics. We show that Rab10 localizes to the ER and to dynamic ER-associated structures that track along microtubules and mark the position of new ER tubule growth. Rab10 depletion or expression of a Rab10 GDP-locked mutant alters ER morphology, resulting in fewer ER tubules. We demonstrate that this defect is due to a reduced...
