Research Abstract

Endocytosis performs a wide range of functions in animals and plants. Clathrin-coated vesicle (CCV) formation is an initial step of endocytosis, and in animal cells is largely achieved by dynamins. However, little is known of its molecular mechanisms in plant cells. To identify dynamin-related proteins (DRPs) involved in endocytic CCV formation in plant cells, we compared the behaviors of two structurally different Arabidopsis DRPs, DRP2B and DRP1A. DRP2B and DRP1A colocalized and assembled/disassembled together at the plasma membrane in Arabidopsis cells. DRP2B and DRP1A participate together in endocytic CCV formation in Arabidopsis cells despite the difference of their molecular properties.
