Motilin receptor is a G protein-coupled receptor (previously GPCR38)^[3]^[4]^[5] that binds motilin.^[6]^[7] It was first cloned in 1999 by Merck Laboratories.^[8] and scientists have since been searching for compounds to modify its behavior.^[9]

The primary structure of the motilin receptor consists of 412 amino acids,^[8] while its tertiary structure resembles a golf club.^[10] The protein C-terminal protein protects from enzymatic degradation, while the N-terminal is essential for binding.^[10]
