    ..Other neurons are relatively unaffected by overexpression. Collectively, these observations indicate that axonal growth is sensitive to the levels of P60-katanin, but that other factors contribute to modulating this sensitivity. ..

    ..Our model can explain how Ca(2+) regulates both severing and ATP hydrolysis activity, because the Ca(2+) -binding site on the N-terminal domain moves close to the AAA domain during MT severing. ..

    ..Our results suggest that NDEL1 is essential for mitotic cell division and neuronal migration not only via regulation of cytoplasmic dynein function but also by modulation of katanin p60 localization and function. ..

    ..We propose that the ASPM-katanin complex controls microtubule disassembly at spindle poles and that misregulation of this process can lead to microcephaly. ..
