Protein tyrosine phosphatase 1

WebbTyrosine-protein phosphatase non-receptor type 1 also known as protein-tyrosine phosphatase 1B (PTP1B) is an enzyme that is the founding member of the protein tyrosine phosphatase (PTP) family. In humans it is encoded by the PTPN1 gene. WebbDEP-1 is a tumor suppressor that dephosphorylates and thereby stabilizes EGFR by hampering its ability to associate with the CBL-GRB2 ubiquitin ligase complex. Data reveal PTPN2, PTPRJ and PTEN as potent regulators of Akt signalling which contribute to ameliorating the consequences of oncogenic K-Ras activity.
