Comments
  • FUNCTION: Required for T-cell activation through the antigen receptor. 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 an dephosphorylates SKAP1 and FYN.
  • CATALYTIC ACTIVITY: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
  • SUBUNIT: Binds GANAB and PRKCSH (By similarity). Interacts with SKAP1.
  • SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing. At least 8 isoforms are produced.
    Name1
    Isoform IDP08575-1
    This is the isoform sequence displayed in this entry.
    Name2
    Isoform IDP08575-2
    Features which should be applied to build the isoform sequence: VSP_007780.
  • DOMAIN: The first PTPase domain interacts with SKAP1.
  • PTM: Heavily N- and O-glycosylated.
  • 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]. SCID refers to 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 with SCID present in infancy with 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.
  • DISEASE: 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.
  • SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.
  • SIMILARITY: Contains 2 fibronectin type-III domains.
  • SIMILARITY: Contains 2 tyrosine-protein phosphatase domains.
  • WEB RESOURCE: Name=PTPRCbase; Note=PTPRC mutation db; URL="http://bioinf.uta.fi/PTPRCbase/";.
  • WEB RESOURCE: Name=Wikipedia; Note=CD45 entry; URL="http://en.wikipedia.org/wiki/CD45";.
