Research Abstract |
In order to address the regulatory mechanisms of smooth muscle contraction and relaxation, we aimed to develop a novel highly sensitive method to analyze phosphorylation signals. We are attempting to quantify MYPT1 phosphorylation in bovine ciliary muscle by using phos-tag electrophoresis. High level of myosin phosphorylation was observed in Carbachol-contracted ciliary muscle. Contrary to our expectations, myosin phosphorylation remained at high level even in the resting state. These results suggest that there could be an unknown Ca^<2+>-dependent factor that regulates bovine ciliary muscle contraction rather than myosin phosphorylation.
