Purification of Membrane Proteins Overexpressed in Saccharomyces cerevisiae.
Methods in molecular biology (Clifton, N.J.)(2022)
Abstract
Membrane protein (MP) functional and structural characterization requires large quantities of high-purity protein for downstream studies. Barriers to MP characterization include ample overexpression, solubilization, and purification of target proteins while maintaining native activity and structure. These barriers can be overcome by utilizing an efficient purification protocol in a high-yield eukaryotic expression system such as Saccharomyces cerevisiae. S. cerevisiae offers improved protein folding and posttranslational modifications compared to prokaryotic expression systems. This chapter contains practices used to overcome barriers of solubilization and purification using S. cerevisiae that are broadly applicable to diverse membrane associated, and membrane integrated, protein targets.
