WitrynaThe receptor is a prototype of the antibody that the B cell is prepared to produce. The B cell receptor (BCR) can only bind antigens. It is the heterodimer of Ig alpha and Ig beta that enables the cell to transduce the signal and respond to the presence of antigens on the cell surface. The signal generated causes the growth and proliferation of ... The B cell receptor (BCR) is a transmembrane protein on the surface of a B cell. A B cell receptor is composed of a membrane-bound immunoglobulin molecule and a signal transduction moiety. The former forms a type 1 transmembrane receptor protein, and is typically located on the outer surface of these lymphocyte cells.
