PRO name IgA2 B cell receptor complex (human)
Synonyms
PRO-short-label: EXACT: hIgA2/B-cell-receptor
Other: EXACT: membrane-bound IgA2 (human) | surface IgA2 (human)
BROAD: membrane-bound IgA (human) | surface IgA (human)
Definition An IgA2 immunoglobulin complex that is present in the plasma membrane of B cells and is composed of two identical immunoglobulin heavy chains of the membrane-bound isoform of the IgA2 isotype, two identical immunoglobulin light chains (kappa or lambda), and a signaling subunit, a heterodimer of the Ig-alpha and Ig-beta proteins.
