Cd19

  • Official Full Name

    CD19 molecule

  • Overview

    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.

  • Synonyms

    B4;CVID3;MGC12802;CD19;B-lymphocyte antigen CD19;OTTHUMP00000122551;differentiation antigen CD19;T-cell surface antigen Leu-12;B-lymphocyte surface antigen B4
