Abstract excerpt
Extracellular cAMP stimulates the rapid tyrosine phosphorylation and nuclear translocation of the DICTYOSTELIUM: STAT protein Dd-STATa. Here we show that it also induces serine phosphorylation by GskA, a homologue of glycogen synthase kinase-3 (GSK-3). Tyrosine phosphorylation occurs within 10 s of stimulation, whereas serine phosphorylation takes 5 min, matching the kinetics observed for the cAMP regulation of...
