    ..1R ternary complex in vitro. Furthermore, the binding of 4.1R to 1-301 is greatly enhanced by PIP(2), implying the existence of a regulatory switch in the cell. ..

    ..We suggest that ?I-spectrin is a synaptic protein that can modulate both the morphological and functional dynamics of dendritic spines, perhaps via interaction with actin and Rac3. ..

    ..It is concluded that a fraction of band 3 is attached to the erythrocyte cytoskeleton through association with ankyrin, which in turn is bound to spectrin. ..

    ..These results suggest that aciculin is associated with dystrophin and may interact with both the N- and C-terminal domains of dystrophin. ..
