NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is the founding member of the protein tyrosine phosphatase (PTP) family, which was isolated and identified based on its enzymatic activity and amino acid sequence. PTPs catalyze the hydrolysis of the phosphate monoesters specifically on tyrosine residues. 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. This PTP has been shown to act as a negative regulator of insulin signaling by dephosphorylating the phosphotryosine residues of insulin receptor kinase. This PTP was also reported to dephosphorylate epidermal growth factor receptor kinase, as well as JAK2 and TYK2 kinases, which implicated the role of this PTP in cell growth control, and cell response to interferon stimulation.

Uniprot Description
PTP1B: a non-receptor phospho-tyrosine protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation and inactivation of PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades. May regulate the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion. Negatively regulates insulin signaling by dephosphorylating the phosphotyrosine residues of insulin receptor. Also reported to dephosphorylate integrin, epidermal growth factor receptor, JAK2 and TYK2, regulating cell growth control and the cellular response to interferon. May regulate the hepatocyte growth factor receptor signaling pathway through dephosphorylation of MET. PTP1B knockout mice show resistance to dietary weight gain and enhanced insulin sensitivity, suggesting a possible role in treatment of obesity as well as type 2 diabetes.

Product Notes
The PTPN1 ptpn1 (Catalog #AAA7118577) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Phospho-PTPN1 (S50) Antibody reacts with Human, Mouse, Rat, Monkey and may cross-react with other species as described in the data sheet. AAA Biotech's PTPN1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC), ELISA (EIA). WB: 1:500-1:2000 IHC: 1:100-1:300 ELISA: 1:40000. Researchers should empirically determine the suitability of the PTPN1 ptpn1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "PTPN1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
