Divergence of human alpha-chain constant region gene sequences. A novel recombinant alpha 2 gene.
1 Jun 1994
Abstract excerpt
IgA is the major Ig synthesized in humans and provides the first line of defense at the mucosal surfaces. The constant region of IgA heavy chain is encoded by the alpha gene on chromosome 14. Previous studies have indicated the presence of two alpha genes, alpha 1 and alpha 2, with alpha 2 existing in two allotypic forms, alpha 2 m(1) and alpha 2 m(2). Here we report the cloning and complete nucleotide sequence...
