Characterization of four novel ϵ chain mRNA and a comparative analysis of genes for immunoglobulin E in rodents and man

The nucleotide sequence of the 3′ region of the E chain gene for human IgE is presented. A comparison of the entire region from 5′ of exon C1 to the M2 exon of the mouse, rat and human ϵ chain genes shows that the overall structure of the ϵ chain gene have changed only minimally during the 60‐70 million years of evolutionary separation between rodents and man.
