Since the first edition of Guidebook to Cytoskeletal and Motor Proteins many new and important discoveries have been made on the structure and function of proteins involved in the microfilament, microtubule and intermediate filament systems in cells. Even specialists in the field have found itdifficult to keep up with the information that has emerged in recent years on this diverse range of eukaryotic proteins, their genes, and the roles that they play in cell structure, motor function and signalling. The Sambrook and Tooze guidebooks provide succinct and up-to-date information onparticular classes of important biological molecules, accompanied by short bibliographies, which enable both specialists and newcomers to the field to gain access to unfamiliar work. This volume begins with a comprehensive catalogue of the structure and function of cytoskeletal actin, tubulin, andintermediate filaments and their associated proteins There is further coverage of proteins which are involved in 'New Filament Systems'. A section on 'Molecular Motors and Associated Proteins' details all that is currently known about the major motor protein families and the proteins which areassociated with them in the motor complex. In addition, a section on 'Organelle Structural Proteins' describes the roles these proteins have in efficient intracellular communication and function.
