    Torsten Wittmann
    The Scripps Research Institute, Department of Cell Biology, 10550 North Torrey Pines Road, La Jolla, California 92037, USA
    Curr Biol 15:R126-9. 2005
    ..Two recent papers on one such protein, CLIP-170, provide new insights into the cellular functions of +TIPs as well as the mechanism by which they track microtubule ends...
