  • Target

    • Function

      Protein 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 disease

      Defects 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.

    • ab23910 staining the CD45 in Mouse brain tissue sections by IHC-Fr (frozen sections). Tissue was fixed with acetone and blocked with 5% BSA for 10 hours at 20°C. Samples were incubated with primary antibody (1/100) for 1 hour at 20°C. An Alexa Fluor®-conjugated goat anti-rat IgG polyclonal (1/300) was used as the secondary antibody.

    We recommend that alignment should be over 85% to predict that an antibody will detect in a different species. The alignment between the mouse protein and the human immunogen is below the threshold at 80%. I would therefore suggest this antibody would not detect in this species.

    However, we do have two antibodies available which will be able to detect in this two applications in mouse:
