Immunoglobulin Gene Diversification

Abstract excerpt

Three processes alter genomic sequence and structure at the immunoglobulin genes of B lymphocytes: gene conversion, somatic hypermutation, and class switch recombination. Though the molecular signatures of these processes differ, they occur by a shared pathway which is induced by targeted DNA deamination by a B cell-specific factor, activation induced cytidine deaminase (AID). Ubiquitous factors critical for DNA...
