General description

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.

Specificity

This antibody only reacts with the oxidized form.

Quality

Evaluated by Immunoprecipitation in recombinant PTP1B (aa 1-321; WT and CASA mutant) and scFv45 cell lysate.

Immunoprecipitation Analysis: 278 ng of this antibody detected PTP1B (Oxidized) in recombinant PTP1B (aa 1-321; WT and CASA mutant) and scFv45 cell lysate.

Target description

~37 kDa observed. The calculated molecular weight is 50kDa however PTP1B has been observed at ~37 kDa since it is a truncated form (aa 1-321). Uncharacterized band(s) may appear in some lysates.
