A 3.4-kilobase DNA fragment containing the gene coding for the Eɑ chain of an Ia (I region-associated) antigen from the BALB/c mouse has been sequenced. It contains at least three exons, which correlate with the major structural domains of the Eɑ chain-the two external domains al and ɑ2, and the transmembrane-cytoplasmic domain. The coding sequence of the mouse Eɑ gene shows striking homology to its human counterpart at the DNA and protein levels. The translated ɑ2 exon demonstrates significant similarity to β_2-microglohulin, to immunoglobulin constant region domains, and to certain domains of transplantation antigens. These observations and those of others suggest that the Ia antigen, transplantation antigen, and immunoglohulin gene families share a common ancestor.
