exposure to pma increased the amount of 32p incorporation into several phosphoproteins , including two cytosolic proteins with molecular weights of 30,000 ( pi 5.5 and 5.7 ) , an acidic 80,000 molecular weight protein ( pi 4.5 ) present in both the cytosolic and membrane fractions , and two cytoskeletal proteins with molecular weights of 60,000 ( pi 5.3 ) and 55,000 ( pi 5.6 ) , identified as vimentin and glial fibrillary acidic protein , respectively .
