Amino-terminal arginylation targets endoplasmic reticulum chaperone BiP for autophagy through p62 bi
(a) BiP is N-terminally arginylated at Nt-Glu 19. HeLa cells were transfected with a plasmid expressing X-BiP–Flag, wherein the Flag epitope was inserted between the BiP protein body and the C-terminal KDEL sequence. (b) Schematic diagrams of full-length ...
