Localization of heat shock protein 20 in swine carotid artery

摘要

BackgroundCyclic nucleotides can relax vascular smooth muscle by mechanisms distal to myosin regulatory light chain (MRLC) phosphorylation. This mechanism, termed relaxation without MRLC dephosphorylation, may be regulated by ser¹⁶ phosphorylation of heat shock protein 20 (HSP20).
