Caution:Epitope 1 , mapped in PubMed:16785532 , is predicted to be buried in the membrane. Its accessibility to the extracellular space , and thus to antibody recognition , is not explained. ,Function:This protein may be involved in the regulation of B-cell activation and proliferation. ,online information:CD20 entry ,pharmaceutical:Monoclonal antibodies (mAb) against CD20 are used to treat B-cell non-Hodgkin's lymphoma (NHL) . These antibodies include Rituximab (Mabthera) , Britumomab (Zevalin) and Tositumomab (Bexxar) . CD20 engaged by mAb can generate transmembrane signals capable of directly controlling cell growth and triggering cell death in certain tumors. Alternatively , mAb can mediate complement-dependent cytotoxicity. ,PTM:Phosphorylated. Might be functionally regulated by protein kinase (s) . ,similarity:Belongs to the MS4A family. ,tissue specificity:Expressed on B-cells. ,
