A Model for ERD2 Function in Higher Plants

open access: yesFrontiers in Plant Science, 2020
ER lumenal proteins have a K(H)DEL motif at their C-terminus. This is recognized by the ERD2 receptor (KDEL receptor in animals), which localizes to the Golgi apparatus and serves to capture escaped ER lumenal proteins.
