GO:0019815 B cell receptor complex

Term Information

ID GO:0019815
Name B cell receptor complex
Ontology Cellular Component
Definition An immunoglobulin complex that is present in the plasma membrane of B cells and that in its canonical form is composed of two identical immunoglobulin heavy chains and two identical immunoglobulin light chains and a signaling subunit, a heterodimer of the Ig-alpha and Ig-beta proteins.
Comment Note that an immunoglobulin complex has the function of antigen binding if a suitable antigen is available.
