  • FunctionProtein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN.
  • Involvement in diseaseDefects in PTPRC are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T(-)B(+)NK(+) SCID) [MIM:608971]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.
    Genetic variations in PTPRC are involved in multiple sclerosis susceptibility (MS) [MIM:126200]. MS is a neurodegenerative disorder characterized by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in third or fourth decade with intermittent progression over an extended period. The cause is still uncertain.
  • Sequence similaritiesBelongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 2 tyrosine-protein phosphatase domains.
  • DomainThe first PTPase domain interacts with SKAP1.
  • Post-translational
    Heavily N- and O-glycosylated.
  • Cellular localizationMembrane. Membrane raft. Colocalized with DPP4 in membrane rafts.

The immunogen used to produce ab25386 was murine T1M1 (Thy-1-C) cells. This product is not routinely tested for cross reactivity with human; however, this clone was previously confirmed to be negative on human blood when tested by flow cytometry.

Thank you for contacting Abcam and for your interest in ab25386.

Regarding WB, the antibody has not been tested in this application and therefore it is not covered by the Abpromise for WB. IHC-P has been added to the datasheet specifica...

Thanks for the additional information. At this time we have not had experience testing this antibody on rat samples. It has only been tested for reactivity to mouse CD45. Have you tested it on a mouse sample for a positive control?
