Methods Mol Biol. 2023:2627:183-193. doi: 10.1007/978-1-0716-2974-1_10.

Abstract

Olfactory receptors (ORs) form the largest subfamily within class A G protein-coupled receptors (GPCRs). No experimental structural data of any OR is available to date. Homology modeling has become a popular strategy to propose plausible OR models, in order to study the structure-function relationships of the receptors and to aid the discovery and development of ligands capable of modulating receptor activity. In this chapter, we provide a general guideline for OR structure construction, including the collection of candidate templates, structure-based sequence alignment, 3D structure construction, ligand docking, and molecular dynamic simulation.

Keywords: G protein-coupled receptors; Homology modeling; Molecular Dynamics; Odorants; Olfactory receptors.
