Regulation Of Katanin Activity On Microtubules, Madison A. Tyler
Masters Theses
The cytoskeleton is a dynamic network of microtubules constantly being reorganized to meet the spatiotemporal demands of the cell. Microtubules are organized into subcellular highways to control cell processes such as cell division, cargo transport, and neuronal development and maintenance. Reorganization of this intricate network is tightly regulated by various stabilizing and destabilizing microtubule-associated proteins that decorate the network. Katanin p60 is a microtubule destabilizing enzyme from the ATPases Associated with various Activities (AAA+) family. It can both sever and depolymerize microtubules. In order to sever microtubules, katanin recognizes the tubulin carboxy-terminal tails (CTTs) and hydrolyzes ATP. Using super-resolution microscopy …
