Reversible oxidation of the catalytic cysteine of protein-tyrosine phosphatases (PTPs) has emerged as a putative mechanism of activity regulation by physiological cell stimulation with growth factors, and by cell treatments with adverse agents such as UV irradiation. We compared SHP-1 and SHP-2, two structurally related cytoplasmic protein-tyrosine phosphatases with different cellular functions and cell-specific expression patterns, for their intrinsic susceptibility to oxidation by H(2)O(2… CONTINUE READING
