Three spontaneous H-2Db mutants are generated by genetic micro- recombination (gene conversion) events. Impact on the H-2-restricted immune responsiveness


Sequence analysis of the mutant Dbm13, Dbm14, and Dbm24 genes indicate that they differ from the parental Db gene by 4, 1, and 8 nucleotides, respectively. The mutant sequences substituted into Dbm13 and Dbm24 are identical to those found in the Kb gene, at the homologous positions. Thus, similar to the Kb gene, the Db gene is able to undergo micro… (More)
