analysis of radioautograms of cell surface camp-binding proteins from confluent monolayer tumor cells , photoaffinity labeled with [ 32p ] 8-n3-camp and subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed two major 32p-labeled protein bands which were indistinguishable from the 49,000 and 55,000 mol wt regulatory subunits of the cytosolic protein kinase isoenzymes of this cell .
