Physiological function of TRPM4 in vascular smooth muscle cell. Solid red arrows indicate calcium flow; dash red arrows indicate calcium regulation targets. Solid black, deep blue, and orange arrows indicate sodium, potassium, and chloride flow, respectively. Only selected ion channels are shown. CaCCs, calcium-activated chloride channels. PKC, protein kinase C; SR, sarcoplasmic reticulum.
