Fyn is associated with Tau and Tubulin in primary oligodendrocytes. Raft fractions and bottom gradient fractions of sucrose density gradients from primary oligodendrocytes were subjected to immunoprecipitation (IP) using antibodies to Fyn followed by SDS-PAGE (lanes 1, 2) or were analyzed directly by SDS-PAGE (lanes 3,4) followed by Western blot (wb) analysis using monoclonal antibodies against Fyn, Lyn, Tau, and α-Tubulin. Fyn associates with Tau and α-Tubulin in the raft fraction as well as in the bottom gradient fraction. Lyn, which is also found in the raft fraction (Lyn, lane 3), is not associated with this complex, either in the raft fraction (lane 1) or in the non-raft fraction (lane 2).
