RESUMO
The kappa light chain genes from two mutant hybridoma cell lines defective in kappa light chain synthesis were isolated and compared to the wild-type kappa light chain gene. In each case, the mutant kappa light chain genes were found to contain repetitive DNA elements in their intervening sequences that were not present in the intervening sequences of the wild-type kappa light chain gene. These elements were found to be related to the genes of intracisternal A particles. These results suggest that the decreased production of kappa light chain in the mutant cell lines is due to the presence of the intracisternal A particle-related genes.
