      Background InformationCD45 is a receptor-tyrosine phosphatase required for antigen-induced signaling in T-cells and B-cells; its substrates are unknown. Interestingly, it associates with several Src-family tyrosine kinases, which are inhibited by tyrosine phosphorylation in their c-termini, suggesting a mechanism for signaling by CD45.

      ImmunogenPurified T cells from human lymph nodes
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis antibody reacts with the leucocyte common antigen (LCA) complex to be found on lymphocytes, monocytes, granulocytes, thymocytes and malignant T and B cells. No reactivity has been observed with primary or metastatic carcinoma cells. Plasma cells or myeloma cells may have weak expression or be negative for this antigen.
      The LCA comprises of at least 5 isoforms ranging from 180-220 kDa which are produced as a result of alternative splicing of exons A, B or C. CBL 124 recognizes epitopes common to
      all of the isoforms.

      Entrez Gene Number
      Entrez Gene SummaryThe 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, mitotic cycle, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus belongs to receptor type PTP. This gene is specifically expressed in hematopoietic cells. 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. Four alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P08575 # 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.
      SIZE: 1304 amino acids; 147254 Da
      SUBUNIT: Binds GANAB and PRKCSH (By similarity). Interacts with SKAP1.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      DOMAIN: SwissProt: P08575 The first PTPase domain interacts with SKAP1.
      PTM: Heavily N- and O-glycosylated.
      DISEASE: SwissProt: P08575 # Defects in PTPRC are a cause of autosomal recessive severe combined immunodeficiency T-cell-negative/B-cell- positive/NK cell-positive (T(-)/B(+)/NK(+) SCID) [MIM:608971]. SCID refers to a genetically and clinically 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, including Candida albicans, Pneumocystis carinii, and cytomegalovirus, among many others. 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.
      SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily. & Contains 2 fibronectin type-III domains. & Contains 2 tyrosine-protein phosphatase domains.
