No modulation of maximal force-velocity mechanics by phosphorylation in rabbit fibers; leaves open its role at submaximal calcium or in intact cardiac muscle.
Myosin light chain phosphorylation does not appear to modulate actomyosin interaction mechanics in permeabilized rabbit psoas fibers under maximal calcium activation.
Sweeney et al. (1985) studied this question.
