Supplementary information

IgA1 also known as Immunoglobulin A1 is an important component of the immune system. This protein mainly exists in mucous membranes where it plays an important role in immune function. IgA1 has a mass of approximately 160 kDa and is expressed in various tissues including the respiratory and gastrointestinal tracts. IgA1 is a subclass of immunoglobulin A (IgA) and is characterized by its heavy chain constant region which distinguishes it from other immunoglobulin subclasses.
Biological function summary

IgA1 acts as a first line of defense in the immune system by binding to pathogens and neutralizing them. It exists as a monomer or forms a dimer with the help of the J chain which stabilizes its dimeric form. IgA1 also interacts with the polymeric immunoglobulin receptor (pIgR) for transportation across epithelial cells. This transport allows IgA1 to be present in secretory fluids such as saliva and breast milk providing an important protective function.

Pathways

IgA1 interacts with several pathways involved in immune response and mucosal immunity. One critical pathway is the mucosal antibody response where IgA1 plays a role in preventing infection at mucosal surfaces. The IgA1 protein activates the alternative complement pathway by binding to complement protein C3 which enhances the removal of pathogens. Furthermore IgA1 is associated with the J chain and pIgR in the process of IgA transcytosis across epithelial barriers.

IgA1 has strong connections to IgA nephropathy and celiac disease. In IgA nephropathy IgA1 deposits in glomeruli leading to inflammation and kidney damage. The increased serum levels of IgA1 often with aberrant glycosylation contribute to disease development. In celiac disease IgA1 reacts with tissue transglutaminase causing an immune response that damages the small intestine's lining. In both disorders the interactions between IgA1 and other proteins such as tissue transglutaminase in celiac disease highlight its involvement in pathological processes.

Target data

Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed : 20176268, PubMed : 22158414). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for a particular antigen (PubMed : 17576170, PubMed : 20176268). Ig alpha is the major immunoglobulin class in body secretions (PubMed : 2241915).
