Phosphotyrosine phosphatase
WebApr 1, 1987 · Abstract. A unique phosphatase that selectively hydrolyzed phosphotyrosine and 2′-AMP at alkaline pH and pp-nitrophenylphosphate, 3′-AMP, 2′-GMP, and 3′-GMP; the ratio of its activities with these substrates was 100: 96: 115: 68: 39: 25: 16. Its K m values for L-phosphotyrosine, 2′-AMP, and p-nitrophenylphosphate were 0.8 × 10 −4 M ... Webnon-receptor protein tyrosine phosphatase of Src homology phosphotyrosine phosphatase 2 (Shp2), has been previously well interpreted as a proto-oncogene in a variety of malignancies. However, the tumor suppressor role of Shp2 has also been reported. The present study was conducted to investigate the role of Shp2 expression and its associated
