Biological Functions of Microtubules and Related Structures is a compendium of papers presented at the 13th Oji International Seminar on The Biological Functions of Microtubules and Related Structures, held at Komaba Eminence in Tokyo in November, 1981. The papers discuss the molecular function of tubulin in various biological processes or events. The book is divided into six sections focusing on the various aspects of the functions and structures of microtubules -- the biochemistry and molecular biology of tubulin, including regulation of microtubule assembly; microtubule-dynein systems and other proteins in cell motility; microtubules and related proteins in mitosis; the interactions of cytoskeletal components; the cytoskeleton; and microtubules in membrane functions and transport. Biochemists, biologists, and molecular biologists will find the book interesting.
