Catchbond mediated oscillations in motor-microtubule complexes
Sougata Guha ; MIthun K. Mitra ; Ignacio Pagonabarraga ; Sudipto Muhuri ;
Date 10 May 2020
AbstractThe activity of motors along with passive crosslinkers play a vital role in maintaining the integrity of the mitotic spindle structure and in generating spontaneous oscillations. While the structural features and properties of the individual motors are well characterized, their implications on the functional behaviour of motor-microtubule complexes is more involved. 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.
