CD19, also known as B-Lymphocyte Surface Antigen B4, belongs to the Ig superfamily which is expressed on the surface of all B-lymphoid cells with the exception of terminally differentiated plasma cells. CD19 is involved as a signal-transducing receptor in the control of differentiation as well as proliferation. CD19 is as an adaptor protein which drafts cytoplasmic signaling proteins to the membrane and operates within the CD19/CD21 complex to decrease the threshold for B cell receptor signaling pathways. CD19 is present on all B cells, and therefore is a biomarker for lymphoma diagnosis, B lymphocyte development and can be used as a target for leukemia immunotherapies.
CD19 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 510 amino acids (21-291a.a.) and having a molecular mass of 57.0kDa. (Molecular size on SDS-PAGE will appear at approximately 50-70kDa).CD19 is expressed with a 239 amino acid hIgG-His tag at C-Terminus and purified by proprietary chromatographic techniques.
| UniProt Protein Function: | Assembles with the antigen receptor of B-lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. |
| NCBI Summary: | Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
