PRO name	IgA1 immunoglobulin complex (human)
Synonyms	PRO-short-label: EXACT: hIgA1 Other: NARROW: IgA1 antibody (human) BROAD: IgA antibody (human)
Definition	An IgA immunoglobulin complex that in monomeric form is composed of two identical immunoglobulin heavy chains of the IgA1 isotype and two identical immunoglobulin light chains (kappa or lambda) held together by disulfide bonds, and sometimes complexed with J chain or J chain and secretory component. An IgA1 immunoglobulin complex may be embedded in the plasma membrane or present in the extracellular space, in mucosal areas or other tissues, or circulating in the blood or lymph.
