Potassium Chloride 60-63 tyrosine hydroxylase Rattus norvegicus 33-53 1979980-1 1990 The phosphorylation and activation of tyrosine hydroxylase was examined in PC12 cells following depolarization with KCl or treatment with nerve growth factor. Potassium Chloride 116-119 tyrosine hydroxylase Rattus norvegicus 38-58 1979980-8 1990 We conclude that serine 31 is phosphorylated during KCl depolarization and nerve growth factor treatment of PC12 cells and that this phosphorylation is responsible for the activation of tyrosine hydroxylase. Potassium Chloride 52-55 tyrosine hydroxylase Rattus norvegicus 186-206
