Disease-associated MYH11 tail variants disrupt vascular smooth muscle myosin II filament dynamics and cell mechanics
Smooth muscle myosin II (SMII), encoded by MYH11, is the principal motor driving vascular smooth muscle cell (VSMC) contraction. How disease-associated MYH11 variants alter SMII behavior in living cells remains poorly understood. We directly visualized two human MYH11 tail variants in VSMCs: pathogenic K1256del and a variant of uncertain significance A1839V, identified in a patient with severe…
