Before revision:  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:  The results reported here elucidate the central role of catchbond mediated mechanism in fashioning a distinctive stability behaviour and oscillations in motor-microtubule complexes in biologically relevant regimes. Hitherto, it was thought that the primary functional role of the biological catchbond was to improve surface adhesion of bacteria and cell when subjected to external forces or flow field. Instead our theoretical study shows that the imprint of this catch bond mediated physical mechanism would have ramifications for whole gamut of intracellular processes ranging from oscillations in mitotic spindle oscillations to activity in muscle fibres .
