Figure 6

Schematic representation of the proposed model of regulation of breast cancer cell migration via CD44 localisation in lipid rafts. When CD44 is affiliated with lipid rafts via palmitoylation of its cysteine residues, it is sequestered from binding its cytoplasmic binding partners and thus migration is restrained. However, when CD44 translocates outside lipid rafts in its de-palmitoylated state, its cytoplasmic tail is free to bind its cytoskeletal partners, subsequently facilitating cell migration.
