Calcium and Potassium Channel Regulation by Protein Phosphorylation in Smooth Muscle Cells of Guinea Pig Taenia Coli
Generally speaking, Ca2+ influx through membrane in smooth muscle cells may play a crucial role in Excitation-Contraction Coupling. Mammalian smooth muscle cells are universally endowed with a lot of L-type, dihydropyridine-sensitive voltage-dependent Ca2+ channels and various kinds of K+ channels. Actually, Ca2+ conductances are increased by membrane depolarization causing Ca2+ influx and subsequent contraction.
