We have investigated the effect of vanadate on the phosphoserine- and phosphotyrosine-specific phosphoprotein phosphatase activities of A-431 cell membranes and have found that micromolar concentrations of vanadate strongly inhibit the membrane-dependent dephosphorylation of histones containing phosphotyrosine but that they do not inhibit the dephosphorylation of histones containing phosphoserine and phosphothreonine. In addition, the dephosphorylation of endogeneous membrane proteins of A-431 cells (which are known to be phosphorylated at tyrosine residues) was inhibited by vanadate. These results show that vanadate is a potent and selective inhibitor of phosphotyrosyl-protein phosphatase.
