Human Gene PTPRC (ENST00000348564.11) from GENCODE V39
  Description: Homo sapiens protein tyrosine phosphatase receptor type C (PTPRC), transcript variant 2, mRNA. (from RefSeq NM_080921)
RefSeq Summary (NM_080921): The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitosis, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus is classified as a receptor type PTP. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq, Jun 2012].

DESCRIPTION: RecName: Full=Receptor-type tyrosine-protein phosphatase C; EC=; AltName: Full=Leukocyte common antigen; Short=L-CA; AltName: Full=T200; AltName: CD_antigen=CD45; Flags: Precursor;
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. Dephosphorylates LYN, and thereby modulates LYN activity (By similarity).
CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.
SUBUNIT: Binds GANAB and PRKCSH (By similarity). Interacts with SKAP1. Interacts with DPP4; the interaction is enhanced in a interleukin-12-dependent manner in activated lymphocytes.
INTERACTION: P04626:ERBB2; NbExp=2; IntAct=EBI-1341, EBI-641062; P06239:LCK; NbExp=2; IntAct=EBI-1341, EBI-1348; P06240:Lck (xeno); NbExp=2; IntAct=EBI-1341, EBI-1401; Q02763:TEK; NbExp=3; IntAct=EBI-1341, EBI-2257090;
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. Membrane raft. Note=Colocalized with DPP4 in membrane rafts.
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]. 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.
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.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
