General description
Research Area: Cell Signaling
Protein tyrosine phosphatase, non-receptor type 2 (PTPN2), is one of the most abundant mammalian tyrosine phosphatase. The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. By virtue of protein tyrosine phosphatase activity, PTPN2 is known to be a signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation involved in cell communication and signal transduction.

Biochem/physiol Actions
Protein tyrosine phosphatase, non-receptor type 2 (PTPN2) regulates interferon signaling and the endoplasmic reticulum stress response in pancreatic β-cells during autoimmune diabetes. It serves as a crucial prognostic marker that influences the progression of pancreatic adenocarcinoma (PAAD) by activating the JAK-STAT signaling pathway. Silencing PTPN2 leads to a significant reduction in PAAD cell growth, migration, and invasion, while also triggering cell cycle arrest and apoptosis in PAAD cells.

PTP-S2/TC45 is a nuclear protein tyrosine phosphatase, which induces p53-dependent apoptosis. Here we show that the p53 protein level increased in MCF-7 cells in response to PTP-S2 overexpression. PTP-S2-induced p53 protein was transcriptionally active and it could activate caspase-1 gene

In the previous study, we demonstrated that the nuclear isoform of T-cell protein-tyrosine phosphatase (TC-PTP) dephosphorylated and deactivated signal transducer and activator of transcription 5a (STAT5a) and STAT5b, thereby negatively regulating prolactin (PRL)-mediated signaling pathway. In this study, we examined
