Challenges passive Tβ4 sequestration model; extends actin dynamics concepts but leaves open in vivo cardiovascular relevance.
Tbeta 4 is not merely a passive G-actin sequestering protein; at high concentrations, it interacts with F-actin, altering filament structure and actin assembly dynamics.
Carlier et al. (1996) studied this question.
