Cytoskeleton molecular motor functions
WebThe cytoskeleton provides the cell with an inner framework and enables it to move and change shape. The myosin and kinesin superfamilies are diverse, with about 40 genes … WebThe principal mechanism by which molecular motors accomplish these diverse functions is binding to and moving along cytoskeletal filaments (either microtubules or actin filaments) by transducing the chemical energy available from the hydrolysis of ATP into mechanical work (Block, 2007; Gennerich and Vale, 2009; Schliwa and Woehlke, 2003 ).
