Nettet1. nov. 1991 · Motor proteins in cell division Abstract The movements of eukaryotic cell division depend upon the conversion of chemical energy into mechanical work, which in turn involves the actions of motor proteins, molecular transducers that generate force and motion relative cytoskeletal elements. NettetMany cytoskeletal and signaling proteins cooperate to assemble and organize the central spindle. These include the chromosomal passenger complex (CPC), the microtubule-associated protein (MAP) protein regulator of cytokinesis 1 (PRC1), and at least three kinesin-like motors: KIF4A, KIF20A, and KIF23 (Table 1).
