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.


This antibody recognizes the catalytic domain of PTP1B.


Epitope: Catalytic domain

Recombinant protein corresponding to the catalytic domain of human PTP1B.


Anti-PTP1B Antibody, clone FG6-1G is an antibody against PTP1B for use in Western Blotting, Immunoprecipitation.
