The catalysis of phosphate removal from a phosphotyrosine using cysteine as a nucleophile and proceed by means of a thiol-phosphate intermediate. Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity. Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
