TPH2 is phosphorylated by protein kinase A at Ser19 and Ser104, and by Ca2+/calmodulin dependent protein kinase II at Ser19, phosphorylation at Ser19 activates TPH2 by about 30%, Ser19 is phosphorylated to a stoichiometry of up to 50% in HEK-293 cells expressing TPH2, overview, in vivo phosphorylation in transiently transfected HEK-293 cells occurs with Ser19 phosphorylation stoichiometry of maximally 0.5 mol of phosphate/mol of enzyme subunit in resting cells, which is increasable by cell activation with okadaic acid, overview |
