Ir genes of different high responder haplotypes for staphylococcal nuclease are not allelic.

Journal Article (Journal Article)

The Ir gene controlling high responsiveness to staphylococcal nuclease in the H-2d haplotype has been mapped to the I-A subregion, in contrast to that in the H-2k and H-2a haplotypes, which maps in the I-B subregion. The nonallelic high responder genes also confer differences in fine specificity on the antibodies produced. This nonallelism of Ir genes for the same antigen in different haplotypes is consistent with Ir gene mechanisms involving associative recognition of antigen plus Ia by T lymphocytes. It further suggests that products of different subregions can perform the same function.
