The phosphorylation from UALCAN dataset indicated that significantly altered ptpn6 phosphorylation levels were observed in 6 tumors, including clear cell RCC (CCRCC), LUAD, HNSC, PAAD, colon cancer (CC) and LUSC, and the changes were mainly distributed in three sites, including S10, Y564 and S140 (Fig. 8). The gene discussed is PTPN6; the disease is pancreatic adenocarcinoma.
