V(D)J recombination is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively. The process is a … See more Human antibody molecules (including B cell receptors) are composed of heavy and light chains, each of which contains both constant (C) and variable (V) regions, genetically encoded on three loci: • The … See more Heavy chain In the developing B cell, the first recombination event to occur is between one D and one J gene segment of the heavy chain locus. … See more Key enzymes and components The process of V(D)J recombination is mediated by VDJ recombinase, which is a diverse collection of enzymes.
