NCAM120 interacts with spectrin through rafts. Double immunostaining of (A) CHO cells and (B) hippocampal neurons from NCAM−/− mice transfected with NCAM120, NCAM140, or NCAM180 with antibodies against NCAM and spectrin after treatment with MCD. Note that MCD disrupts the association of spectrin with NCAM120, but not with NCAM140 or NCAM180. Bars: (low power) 10 μm; (high power) 5 μm. (C) Immunoblots of lysates from transfected CHO cells reveal comparable NCAM isoform expression. GFP-transfected cells do not express NCAM. (D) Lysates from NCAM-transfected CHO cells were precipitated with NCAM antibodies (NCAM) or rabbit IgG (Ig) and assayed for spectrin by immunoblotting. Note that MCD treatment prevents the precipitation of spectrin with NCAM120, but not with NCAM140 or NCAM180.
