Epigenetic control of recombination in the immune system.
Immune receptor gene expression is regulated by a series of developmental events that modify their accessibility in a locus, cell type, stage and allele-specific manner. This is carried out by a programmed combination of many different molecular mechanisms, including region-wide replication timing, changes in nuclear localization, chromatin contraction, histone modification, nucleosome positioning and DNA methylation. These modalities ultimately work by controlling steric interactions between receptor loci and the recombination machinery.
