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.
  • Sequence similarities
    Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 2 tyrosine-protein phosphatase domains.
  • Domain
    The first PTPase domain interacts with SKAP1.
  • Post-translational
    modifications
    Heavily N- and O-glycosylated.
  • Cellular localization
    Membrane. Membrane raft. Colocalized with DPP4 in membrane rafts.

Images

  • ab28106 staining the CD45 in Human PBMCs by Flow Cytometry. Cells were prepared by Ficoll-Hypaque isolation of PBMCs from buffy coat. The sample was incubated with the primary antibody (1/25 in PBS + 2% Human serum and 1mM EDTA) for 25 minutes at 4°C.
