Murine I-A beta chain polymorphism: nucleotide sequences of three allelic I-A beta genes

E Choi et al. Science. 1983.

Abstract

The polymorphism of immune response genes plays a critical role in determining the immune capabilities of a particular individual. The molecular nature of this polymorphism was studied by examining the structure of the coding portions of three alleles of the I-A beta chain gene, an immune response gene whose protein product constitutes a subunit of the I-A molecule. Comparison of the I-A beta chains encoded by these alleles revealed an amino acid sequence divergence of 5 to 8 percent. The differences were found to be a series of short alterations clustered in the amino terminal half of the polypeptide.
