Protocol for evaluating S-acylated protein membrane affinity using protein-lipid conjugates.

S-acylation of proteins allows their association with membranes. Here, we present a protocol for establishing a platform for membrane affinity evaluation of S-acylated proteins in vitro. We describe steps for preparing lipid-maleimide compounds, mCherry-p62 recombinant proteins, and total cellular membranes. We then detail procedures for synthesizing protein-lipid conjugates using lipid-maleimide compounds and recombinant proteins and evaluating the membrane affinity of protein-lipid conjugates. For complete details on the use and execution of this protocol, please refer to Huang Xue et al..
