Target Details for CD20

Target: CD20 (MS4A1) (Membrane-Spanning 4-Domains, Subfamily A, Member 1 (MS4A1))

Alternative Name: MS4A1

Background:

Synonyms: B-lymphocyte antigen CD20,B-lymphocyte surface antigen B1,Bp35,Leukocyte surface antigen Leu-16,Membrane-spanning 4-domains subfamily A member 1,CD20,MS4A1,CD20,

Tissue Specificity: Expressed on B-cells.

Background: CD20, also known as MS4A1, is an activated-glycosylated phosphoprotein expressed on the surface of all B-cells beginning at the pro-B phase (CD45R+, CD117+) and progressively increasing in concentration until maturity. It is mapped to 11q12.2. This gene encodes a member of the membrane-spanning 4A gene family. The function of CD20 is to enable optimal B-cell immune response, specifically against T-independent antigens. It is suspected that CD20 acts as a calcium channel in the cell membrane. What's more, this protein may be involved in the regulation of B-cell activation and proliferation.

Sequence Similarities: Belongs to the MS4A family.

Molecular Weight: 35 kDa

Gene ID: 931
