  • 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
    Phosphorylated. Might be functionally regulated by protein kinase(s).
  • Cellular localization
