No direct implications for cardiovascular care; leaves open extension of yeast actin findings to mammalian cardiac cells.
In living cells, profilin promotes rapid actin dynamics by regenerating ATP actin from ADP actin-cofilin generated during filament disassembly.
Wolven et al. (2000) studied Actin cytoskeleton dynamics. Profilin mutations (e.g., pfy1-4) and actin mutations (e.g., act1-157) vs. Wild-type yeast strains was evaluated on Actin filament turnover and cell growth/endocytosis. In living yeast cells, profilin promotes rapid actin dynamics by regenerating ATP actin from ADP actin-cofilin generated during filament disassembly.
