Characterisation of a cell-free synthesised G-protein coupled receptor

Abstract

G-protein coupled receptors are the largest family of integral membrane proteins found within the human genome. They function as receptors and modulators to a wide range of ligands and responses which are crucial for human health. GPCR study, specifically the investigation of structure and interaction to cognate ligands, is of high priority. Limitations for structural study can be traced in part, to obtaining suitable quantities of recombinant protein. We sought to address the limitations of traditional recombinant technologies by utilising an Escherichia coli based cell-free protein synthesis (CFPS) approach for production of a thermostable neurotensin receptor 1 (en2NTS1).
