• Host: Mouse
• Reactivity: Human
• Clonality: Monoclonal
• Isotype: IgG1, kappa
• Clone Number: HISA43
• Specificity: This MAb is specific to heavy chain of IgA and shows minimal cross-reaction with heavy chains of other immunoglobulins. It is reactive with both IgA1 and IgA2 subclasses of Alpha heavy chain. It reacts with the third constant domain (CH3) of the alpha chain of IgA molecules. Immunoglobulins are four-chain, Y-shaped, monomeric structures comprised of two identical heavy chains and two identical light chains held together through inter-chain disulfide bonds. The chains form two domains, the Fab (antigen binding) fragment and the Fc (constant) fragment. Immunoglobulin A (IgA) is the main protein of the mucosal immune system. It is generated by B-cells in gut-associated lymphoid tissues. Daily production of IgA exceeds that of any of the other immunoglobulins. IgA exists mainly in dimers but can also exist as polymers or as monomers. Dimers and polymers contain a joining (J) chain that can be bound by the polymeric immunoglobulin receptor (pIgR) for transportation of the molecule to mucosal surfaces. The most common feature of plasmacytomas, and certain non-Hodgkin's lymphomas is the restricted expression of a single heavy chain class. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is clonal and therefore malignant.

Uniprot Description

IGHA1: Ig alpha is the major immunoglobulin class in body secretions. It may serve both to defend against local infection and to prevent access of foreign antigens to the general immunologic system. A chromosomal aberration involving IGHA1 is found in multiple myeloma (MM) cell lines. Translocation t(1;14)(q21;q32) that forms a FCRL4-IGHA1 fusion protein.

Protein type: Immunoglobulin superfamily

Chromosomal Location of Human Ortholog: 14q32.33

Cellular Component: external side of plasma membrane; extracellular region; extracellular space

Molecular Function: antigen binding

Biological Process: antibacterial humoral response; B cell receptor signaling pathway; complement activation, classical pathway; glomerular filtration; innate immune response; phagocytosis, engulfment; phagocytosis, recognition; positive regulation of B cell activation; receptor-mediated endocytosis; retinal homeostasis
