Supplementary Table 3 Sequences of the N-terminal regions of ER-residing proteins whose N-terminal Asp and Glu residues are evolutionarily conserved.

From: Amino-terminal arginylation targets endoplasmic reticulum chaperone BiP for autophagy through p62 binding

Shown in red are the signal peptides that are removed by the signal peptide peptidase complex on translocation into the ER lumen. The resulting Asp and Glu residues exposed on the N-termini of mature proteins are indicated in blue.
