Abstract

The aim is to determine the nature of detailed molecular interactions between the proteins involved in thin filament regulation of striated muscles, using the only genetic system in which both direct selection for mutants affecting this system and their biochemical/physiological analysis are currently possible - namely the indirect flight muscles (IFMs) of Drosophila melanogaster. Mutations in the troponin and tropomyosin genes which disrupt thin filament regulation or suppress the effects of such mutations will be sought. Sites of interaction between the proteins in this complex will be identified by sequencing the mutant genes. The roles of the different proteins or protein domains in calcium or stretch activation will be dissected by biochemical and physiological analyses of the mutants including in vitro motility and skinned fibre mechanics.
