Enhancers of hypermutation.
Immunogenetics - 1 Jan 1996

Abstract excerpt
Hypermutation at the immunoglobulin (Ig) loci increases the mutation rate more than 10(5)-fold over the normal, spontaneous rate. We studied two kinds of cis-acting elements - 3' enhancers and promoters - in a system in which a gene encoding the mu heavy (H) chain (Igm) is transfected in vitro into a cell line with an active Ig mutator. A construct containing a rearranged Igm gene requires the 3' H enhancer for...
