Figure 1: Post-translational modification of µ-Opioid Receptor.
A schematic representation of rat µ-Opioid Receptor showing putative residues that could be post-translationally modified. Each post-translational modification category is represented by a different color. Filled circles represent known PTMs and white circles represent putative PTMs. The residue numbers in rat MOR are indicated above each reside. Since the N40 has been shown to be glycosylated, it is indicated with a branched chain.
