analysis by limited proteolysis with trypsin and chymotrypsin showed that all of the regions in glycogen synthase phosphorylated by casein/glycogen synthase kinase-2 ( ck-2 ) , the catalytic subunit of cyclic amp-dependent protein kinase ( a-kinase ) , fa/glycogen synthase kinase-3 ( fa/gsk-3 ) and phosphorylase b kinase were also phosphorylated by ck-1 .
