A protein kinase activity in chorionated oocytes of Rhodnius prolixus phosphorylates in vitro vitellin (VT), the major yolk protein. Phosphatase inhibitors including NaF, sodium vanadate, beta-glycerophosphate and okadaic acid did not alter the protein phosphorylation profile to a visible extent. Among the exogenous protein substrates tested, casein was readily phosphorylated, but histones were not. Several different protein kinase activators, including cAMP, Ca2+ plus calmodulin, Ca2+ plus… CONTINUE READING
