WebSHP2 (Src homology-2 domain-containing protein tyrosine phosphatase-2) is a non-receptor protein tyrosine phosphatase that removes tyrosine phosphorylation. Functionally, SHP2 serves as an important hub to connect several intracellular oncogenic signaling pathways, such as Jak/STAT, PI3K/AKT, RAS/Raf/MAPK, and PD-1/PD-L1 pathways. Mutations … WebSHP2 is tyrosine-phosphorylated at Y542 and Y580 downstream of RTKs, which is thought to activate SHP2 molecules by releasing them from an autoinhibitory conformation [ 32, 33 ].
