Members of this nascent protein family are characterized by common structural features and similar intron\/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. CD20 \/ MS4A1 is expressed on all stages of B cell development except the first and last. CD20 \/ MS4A1 is present from pre-pre B cells through memory cells; but not on either pro-B cells or plasma cells. It is a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. CD20 \/ MS4A1may be involved in the regulation of B-cell activation and proliferation. Defects in CD20 \/ MS4A1 are the cause of immunodeficiency common variable type 5(CVID5). 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.\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"100μg","offer_id":40692985495610,"sku":"PKSH030304-100","price":1159.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/recombinant-human-cd20-ms4a1-protein-trxa-tag-100-g-elabscience-biotechnology-cell-assays-22373549211706.jpg?v=1752498405","url":"https:\/\/www.msesupplies.com\/en-gb\/products\/recombinant-human-cd20-ms4a1-protein-trxa-tag","provider":"MSE Supplies","version":"1.0","type":"link"}
