Membrane proteins are difficult to study for numerous reasons. The surface of membrane proteins is relatively hydrophobic and sometimes very unstable, additionally requiring detergents for their extraction from the membrane. This leads to challenges at all levels, including expression, solubilization, purification, identification of associated proteins, and the identification of post-translational modifications. However, recent advances in immunoprecipitation technology allow to isolate membrane proteins efficiently, facilitating the study of protein-protein interactions, the identification of novel associated proteins, and to identify post-translational modifications, such as phosphorylation. Here, we describe an optimized immunoprecipitation protocol for plant plasma membrane receptor-like kinases.
