Molecular motors carry out vital functions in all eukaryotic cells. One of these, Cytoplasmic Dynein, is critical during mitosis, migration and cellular trafficking events. We are characterizing several signaling pathways that impinge on dynein function. Our current focus is on their importance in the adult mammalian nervous system and during colon carcinogenesis in mammals.
