肌球蛋白2万道尔顿L链磷酸化与动脉平滑肌的过桥循环密切相关。[在猪的研究中]有证据表明，去磷酸化可以产生附着的、非循环的交叉桥（闩锁桥），这是该组织中维持力的高经济性的原因。
Phosphorylation of the 20,000-dalton L chain of myosin is closely correlated with cross-bridge cycling in arterial smooth muscle. Evidence is presented [in the pig] that dephosphorylation can produce an attached, noncycling cross-bridge (latch-bridge), which is responsible for the high economy of force maintenance in this tissue.
