    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. Dephosphorylates LYN, and thereby modulates LYN activity.
    • Involvement in disease

      Severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive
      Multiple sclerosis
    • 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.

      Asked on Jul 02 2007

      Answer

      Thank you for your patience in this matter. In regards to ab30476 (CD45RA antibody [F8-11-13] (Biotin)), the originator does not know which epitope this antibody is recognizing. However, information available in the literature suggests that it recognizes a 'restricted' epitope present on B lymphocytes and a sub-population of T lymphocytes. Please see the following articles for further information: Dalchau R, Fabre JW. Identification with a monoclonal antibody of a predominantly B lymphocyte-specific determinant of the human leukocyte common antigen. Evidence or structural and possible functional diversity of the human leukocyte common molecule. J Exp Med. 1981 Apr 1;153(4):753-65. PMID: 6166706 Ritter MA, Sauvage CA, Pegram SM, Myers CD, Dalchau R, Fabre JW. The human leucocyte-common (LC) molecule: dissection of leukaemias using monoclonal antibodies directed against framework and restricted antigenic determinants. Leuk Res. 1985;9(10):1249-54. PMID: 2415779 Although ab8217 (CD45RA antibody [MEM-56]) has not been epitope mapped, the originator thinks it is very probable that this antibody could be recognizing a glycosylated epitope. Regarding ab27290 (CD45RA antibody [B-C15] (FITC)) and ab38439 (CD45RA antibody [LT45-M5]), the originators do not have any information on the epitopes that the antibodies are recognizing. I hope this information helps.
