WebDec 3, 2010 · The nonspecific protein labeling technique in Fig. 5 allows estimation of the lipid modification of raft-enriching proteins in isolated plasma membranes. Results suggest that the majority of integral raft proteins require palmitoylation for raft association, whereas ∼30% of raft-associated proteins are GPI-anchored. WebMay 20, 2013 · In polarized cells, attachment of a GPI anchor generally serves as a trafficking signal to target proteins to the apical surface. The saturated nature of the fatty acids attached to the PI moiety enhances insertion of GPI-anchored proteins into lipid raft domains (Figure 1), where they participate in a wide variety of signal transduction pathways.
