pubmed:abstractText |
We have used Abelson murine leukemia virus (A-MuLV) transformed pre-B cell lines to test the hypothesis that the rearrangement potential of a developing B-lymphocyte is dependent on an "opening" of the chromatin structure surrounding immunoglobulin (Ig) genes, thus allowing accessibility to an Ig gene recombinase. The chromatin structures surrounding heavy (H), kappa (kappa), and lambda (lambda) chain constant-region genes were assessed by DNase I sensitivity in A-MuLV transformed cell lines capable of H, kappa or lambda gene rearrangement. Our results indicate that DNase I-sensitive chromatin structures of these Ig constant-region genes correlate closely with the ability of the genes to undergo recombination. We also find that the chromatin structure of an Ig constant-region locus becomes DNase I sensitive before any DNA rearrangement events occur.
