Recombinant expression of human membrane proteins in large quantities remains a major challenge. Expression host is an important variable to screen for high-level production of membrane proteins. Using the green fluorescent protein (GFP) as a reporter, we screened the expression
Journal of molecular biology, 432(18), 5162-5183 (2020-02-28)
Membrane proteins are generally challenging to work with because of their notorious instability. Protein engineering has been used increasingly to thermostabilize labile membrane proteins such as G-protein-coupled receptors for structural and functional studies in recent years. Two major strategies exist.
