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.

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

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
