Correlation of intracellular Ca(2+)-activated proteinase activity and cholesterol content in white sea mussel (Mytilus edulis) membranes at different water saltiness.
Correlation between changes in activity of intracellular Ca(2+)-activated proteinases and cholesterol content in mussels in response to changes in habitat saltiness was detected in mollusks from littoral and sublittoral White sea zones. Calpain activity in mussels decreased in low water saltiness and increased in high saltiness in parallel with decrease in cholesterol content, which attests to decreased microviscosity and modification of permeability of biomembranes. A complex pattern of interactions between metabolic routes in mussels under conditions of different habitat saltiness was detected.
