Description	Anti-PTP1B Antibody, clone FG6-1G
Alternate Names	Tyrosine-protein phosphatase non-receptor type 1 Protein-tyrosine phosphatase 1B PTP-1B
Background Information	PTP1B is the prototypic member of the protein tyrosine phosphatase (PTP) family, which comprises at least 37 proteins. The family is characterized by a catalytic phosphatase domain of approximately 240 amino acids, and includes both transmembrane and cytosolic enzymes. The PTPs have high substrate specificity for phosphotyrosyl proteins. At the primary sequence level, PTPs share little similarity with the protein serine phosphatases, protein threonine phosphatases, or the acid and alkaline phosphatases. PTP1B is a negative regulator of insulin and leptin signal transduction and may be a potential therapeutic target for diabetes and obesity. Insulin also influences the expression of splice variants of PTP1B.

Entrez Gene Number	NP_002818
Entrez Gene Summary	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.
Gene Symbol	PTPN1 PTP1B
Purification Method	Protein G Purified
UniProt Number	P18031
UniProt Summary	FUNCTION: 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. CATALYTIC ACTIVITY: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. SUBUNIT STRUCTURE: Interacts with EPHA3 (phosphorylated); dephosphorylates EPHA3 and may regulate its trafficking and function. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Note: Interacts with EPHA3 at the cell membrane. POST-TRANSLATIONAL MODIFICATION: Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a sulfenamide cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction. Ser-50 is the major site of phosphorylation as compared to Ser-242 and Ser-243. Activated by phosphorylation at Ser-50. SEQUENCE SIMILARITIES: Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily. Contains 1 tyrosine-protein phosphatase domain.

UVA inactivates protein tyrosine phosphatases by calpain-mediated degradation. Gulati, Pawan, et al. EMBO Rep., 5: 812-7 (2004) 2004 Afficher le résumé UV irradiation causes inflammatory and proliferative cellular responses. We have proposed previously that these effects are, to a large extent, caused by the ligand-independent activation of several receptor tyrosine kinases due to the inactivation of their negative control elements, the protein tyrosine phosphatases (PTPs). We examined the mechanism of this inactivation and found that, in addition to reversible oxidation of PTPs, UV triggers a novel mechanism: induced degradation of PTPs by calpain, which requires both calpain activation and substrate PTP oxidative modification. This as yet unrecognized effect of UV is irreversible, occurs predominantly with UVA and UVB, the range of wavelengths in sunlight that reach the skin surface, and at physiologically relevant doses.	15247926
