Cell-free translation system with artificial lipid-monolayer particles as a unique tool for characterizing lipid-monolayer binding proteins

Abstract Methods for functional analysis of proteins specifically localizing to lipid monolayers such as rubber particles and lipid droplets are limited. We have succeeded in establishing a system in which artificially prepared lipid monolayer particles are added to a cell-free translation system to confirm the properties of proteins that specifically bind to lipid monolayers in a translation-coupled manner.
