      Background InformationImmunoglobin M (IgM) antibody is prominent in early immune responses to most antigens and is the predominant response in certain antibody responses such as "natural" blood group antibodies. IgM is the major immunoglobin expressed on surface B lymphocytes. Most of the chronic lymphocytic leukemias, non Hodgkin lymphomas and Burkitt's lymphoma bear surface IgM, whereas plasmocytes from Waldenström's disease bear intracytoplasmic IgM.

      UniProt SummaryFUNCTION: IgM antibodies play an important role in primary defense mechanisms. They have been shown to be involved in early recognition of external invaders like bacteria and viruses, cellular waste and modified self, as well as in recognition and elimination of precancerous and cancerous lesions. The membrane-bound form is found in the majority of normal B-cells alongside with IgD. Membrane-bound IgM induces the phosphorylation of CD79A and CD79B by the Src family of protein tyrosine kinases. It may cause death of cells by apoptosis. It is also found in soluble form, which represents about 30% of the total serum immunoglobulins where it is found almost exclusively as an homopentamer. After the antigen binds to the B-cell receptor, the secreted form is secreted in large amounts.

      SUBUNIT STRUCTURE: Immunoglobulin (Ig) molecules consist of two chains, one heavy chain (which can be alpha, delta, epsilon, gamma or mu) and one light chain (which can be kappa or lambda) each consisting of a variable and a constant region. An IgM molecule contains thus a mu heavy chain combined with either a kappa or a lambda light chains. It is found almost exclusively as an homopentamer in the serum. Membrane-bound IgM molecules are non-covalently associated with heterodimer of CD79A and CD79B.

      SUBCELLULAR LOCATION: Isoform 1: Secreted. Note: During differentiation, B-lymphocytes switch from expression of membrane-bound IgM to secretion of IgM.

      Isoform 2: Cell membrane; Single-pass type I membrane protein.

      POLYMORPHISM: All 4 combinations of the S/G and V/G polymorphisms at positions 191 and 215 have been observed in human mu chains.

      INVOLVEMENT IN DISEASE: Defects in IGHM are the cause of agammaglobulinemia type 1 (AGM1) [MIM:601495]. It is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life. Ref.10
