Target

  • Function
    This protein may be involved in the regulation of B-cell activation and proliferation.
  • Tissue specificity
    Expressed on B-cells.
  • Involvement in disease
    Defects in MS4A1 are the cause of immunodeficiency common variable type 5 (CVID5) [MIM:613495]; also called antibody deficiency due to CD20 defect. CVID5 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
  • Sequence similarities
    Belongs to the MS4A family.
  • Post-translational
    modifications
    Phosphorylated. Might be functionally regulated by protein kinase(s).
  • Cellular localization
    Membrane.

Images

  • Human peripheral blood lymphocytes stained with ab198943 (red line). Human whole blood was processed using a modified protocol based on Chow et al, 2005 (PMID: 16080188). In brief, human whole blood was fixed in 4% formaldehyde (methanol-free) for 10 min at 22ºC. Red blood cells were then lyzed by the addition of Triton X-100 (final concentration - 0.1%) for 15 min at 37ºC. For experimentation, cells were treated with 50% methanol (-20ºC) for 15 min at 4ºC. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab198943, 1/100 dilution) for 30 min at 4ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) Alexa Fluor® 647 (ab199093) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >30,000 total events were collected using a solid-state 25mW red diode laser (635 nm) and 675/30 bandpass filter.

    Gating strategy - lymphocytes.
