Summary
PTPN2 pays a novel role in the regulation of type 1 interferon-stimulated gene expression in cells previously desensitized to Type 1 interferons.
PTPN2 is a nuclear protein tyrosine phosphatase, a potential negative regulator of the PRL-mediated signalling pathway.
Entrez Gene
Summary The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. Members of the PTP family share a highly conserved catalytic motif, which is essential for the catalytic activity. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. Epidermal growth factor receptor and the adaptor protein Shc were reported to be substrates of this PTP, which suggested the roles in growth factor mediated cell signaling. Multiple alternatively spliced transcript variants encoding different isoforms have been found. Two highly related but distinctly processed pseudogenes that localize to chromosomes 1 and 13, respectively, have been reported. [provided by RefSeq, May 2011]
