| Research Abstract |
Muscular filament-forming proteins, namely, myosin heavy chain, actin and tropomyosin from four species of mollusks (cephalopods) have been investigated. As for tropomyosin, those from other species were examined for their structural stability. Primary structure analysis based on cDNA cloning, phylogenetic analysis based on amino acid sequence, and functional and structural analysis based on tertiary structure simulation have revealed the specificity and uniqueness of those contractile proteins. The results obtained suggested that mollusks, especially cephalopods, have evolved protein related to muscle contraction to compensate for their specialized locomotion activities. On the other hand, the properties of myosin heavy chain, etc. would give important information for the effective utilization and processing of mollusks.
