Transient MLC phosphorylation initiates but need not sustain arterial contraction in this model; extends smooth-muscle physiology yet leaves open human relevance.
Myosin light chain phosphorylation is necessary for the activation of arterial muscle contraction but does not need to be maintained during tension development or maintenance.
Bárány et al. (1985) studied this question.
