Opiate Receptors

Abstract

The molecular basis for the observed pharmacological functions of opioid analgesic drugs is defined by multiple opioid receptors.

Keywords: pain; 6‐protein coupled receptor; receptor cloning; gene structure

Figure 1.

Serpentine representation of the deduced amino acid sequence of the μ‐, δ‐ and κ‐opioid receptors. The blue circles represent the amino acids that are common to all three types of opioid receptor. The green circles represent the amino acids that are common to two of the opioid receptors. The open circles represent the amino acids that are different in all three opioid receptors. The leaders indicate the N‐terminus and C‐termini of the receptors.
