摘要: Dynamic trafficking of membrane proteins is crucial for cells to function properly, not unlike a transportation network linking all locations within a city. Understanding regulators in these trafficking routes is thus an important topic. This study reveals a regulatory route through which the tonoplast-associated V-ATPase is transported in Arabidopsis.

Abstract:

Vacuolar trafficking routes and their regulators have recently drawn lots of attention in plant cell biology. A recent study reported the discovery of a plant-specific vacuolar trafficking route, i.e., a direct ER-to-vacuole route, through analysis of VHA-a3 subcellular targeting, a key component for the tonoplast V-ATPases. Our recent findings showed that VHA-a3 targets to the tonoplast through a Rab5-mediated but Rab7-independent pathway, shedding new lights on the unconventional vacuolar trafficking route in plant cells.
