Both PTN and PMA enhance phosphorylation of β-adducin residue 713 and α-adducin residue 724. (Upper) Western blot of lysates from PTN-treated (50 ng/ml, for 15 and 60 min), PMA-tretaed (1 μM, 60 min), or PKCα/β inhibitor-treated (60 min before PTN and PMA treatment) HeLa cells probed with anti-phosphoserine 713 β-adducin and anti-phosphoserine 724 α-adducin antibodies. (Lower) Reprobe of Western blot with an anti-actin-specific antibody.
