Before revision:  We show that the catchbond behaviour of individual dynein motors manifests as a generic mechanism of generating spontaneous oscillations in such complexes. The results reported here elucidate the central role of catchbond mediated mechanism in fashioning a distinctive stability behaviour and oscillations in motor-microtubule complexes , such as mitotic spindles .
After revision:  We show that the catchbond behaviour of individual dynein motors manifests as a generic mechanism of generating spontaneous oscillations in motor-cytoskeletal filament complexes. We obtain the phase diagram to characterize how this novel catch bond mediated mechanism can give rise to bistability and sustained limit cycle oscillations and results in very distinctive stability behaviour and oscillations in motor-microtubule complexes , such as mitotic spindles .
