Figure 1 From: Engineered G protein coupled receptors reveal independent regulation of internalization, desensitization and acute signaling Design of RASSL variants. The design of each RASSL variant is shown on the left. Differences in amino acid sequences of the receptor variants are shown in the C-terminal alignments, right. Sequence derived from the MOR are dark, while KOR sequences are light. All mutated residues are underlined.Back to article page
