Genetic analysis of myosin II assembly and organization in model organisms.

Myosins are a large family of actin-based motor proteins that are involved in a variety of cellular processes. Class II, or conventional, myosins are organized into a number of multi-component structures such as muscle thick filaments, non-muscle filaments and the actomyosin ring during cell division. A number of conditions must be met for the proper assembly and organization of myosin II-containing structures, including the correct stoichiometry of myosin and its associated proteins, and the conformation and regulation of the myosin molecule itself by molecular chaperones and protein kinases. In this review we discuss the use of model organisms in the genetic analysis of the assembly and organization of myosin-containing structures.
