產品介紹 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淋巴細胞標志物
CD20是B細胞特異性抗原,其表達呈細胞類型一種質膜蛋白質,參與信號傳導作用,此抗體識別大多數B細胞上的一種抗原。多用于標記B淋巴細胞及B細胞淋巴瘤。
CD20一般不與T細胞交叉反應,對B細胞淋巴瘤和急慢性淋巴細胞白血病等有較好的細胞特異性,因此在惡性淋巴瘤,尤其是T或B細胞淋巴瘤的分類上,CD20是最常用的B細胞標志。
