- 产品介绍
- 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淋巴细胞标志物
CD20是B细胞特异性抗原，其表达呈细胞类型一种质膜蛋白质，参与信号传导作用，此抗体识别大多数B细胞上的一种抗原。多用于标记B淋巴细胞及B细胞淋巴瘤。
CD20一般不与T细胞交叉反应，对B细胞淋巴瘤和急慢性淋巴细胞白血病等有较好的细胞特异性，因此在恶性淋巴瘤，尤其是T或B细胞淋巴瘤的分类上，CD20是最常用的B细胞标志。
