background: CD20 is a non glycosylated protein with a molecular weight of 35 or 37 kDa depending on the degree of phosphorylation. Although not a member of the tetraspanin superfamily of cell surface receptors, it crosses the cell membrane four times. The CD20 antigen is present on human pre B lymphocytes and on B lymphocytes at all stages of maturation, except on plasma cells. Low level expression of the CD20 antigen has been detected on normal T lymphocytes. The CD20 molecule is involved in regulation of B cell differentiation, presumably via its reported function as a Ca++ channel subunit. Function: This protein may be involved in the regulation of B-cell activation and proliferation Subcellular Location: Membrane; Multi-pass membrane protein. Tissue Specificity: Expressed on B-cells. Post-translational modifications: Phosphorylated. Might be functionally regulated by protein kinase(s). 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. Similarity: Belongs to the MS4A family.

B淋巴細(xì)胞標(biāo)志物 CD20是B細(xì)胞特異性抗原，其表達(dá)呈細(xì)胞類型一種質(zhì)膜蛋白質(zhì)，參與信號傳導(dǎo)作用，此抗體識別大多數(shù)B細(xì)胞上的一種抗原。多用于標(biāo)記B淋巴細(xì)胞及B細(xì)胞淋巴瘤。 CD20一般不與T細(xì)胞交叉反應(yīng)，對B細(xì)胞淋巴瘤和急慢性淋巴細(xì)胞白血病等有較好的細(xì)胞特異性，因此在惡性淋巴瘤，尤其是T或B細(xì)胞淋巴瘤的分類上，CD20是最常用的B細(xì)胞標(biāo)志。 |
