Myosin is associated with GM1-containing lipid rafts. (A) Immunofluorescence localization of myosin and CTB staining of two and four cell stage embryos. Myosin colocalized with 488-CTB labeled lipid rafts at the apical cell surface. Scale bar represents 25µm. (B) Myosin was detected by Western blot in GM1-containing lipid raft fractions (unlabeled lanes left blank). See also Figure S2 in supplemental material.
