Since the mammalian genome does not have 109 genes (105 genes is a better estimate), different models were suggested to explain antibody diversity. In 1965, W. J. Dreyer and J. C. Bennett suggested that a given chain of an immunoglobulin was not the result of one gene, but of a combination of genes, one for the constant region and one for the variable region. In addition, they suggested that a particular organism, in its haploid genome, had only one constant gene but several hundred or thousand variable genes. The nal product would be the result of the action of a combination of one of the variable genes and

the constant gene. Modern recombinant DNA technology has veri ed the essence of that model. In reality, several genes contribute to form the variable regions of the heavy and light chains, given that we are using the word gene for DNA segments that code for a part of the nal heavy or light chain of the immunoglobulin. Genes for the , , and heavy chains are located on chromosomes 2, 22, and 14, respectively, in human beings. Each is a multigene complex. Let us examine the light-chain gene complex as an example of how the DNA must be modi ed to produce the nal protein product ( g. 16.34). The rst step in DNA rearrangement is the joining of a V (variable) and a J (joining) gene in a B cell ( g. 16.34), a process called V-J joining. Since any one of eighty V genes can combine with any one of ve J genes, four hundred different combinations are possible (80 5). Since we expect this to be another example of sitespeci c recombination, as we saw with phage integration in chapter 14, recombinational signal sequences must be anking all genes so that any two can be moved next to each other. Through DNA sequencing, these signals, termed recombination signal sequences, have been determined to be a heptamer (seven bases) and a nonamer (nine bases), separated by twelve bases on one side and twenty-three bases on the other (known as the 12-23 rule; g. 16.35).

Figure 16.34 The complex for the human light chain is composed of about eighty variable genes (V 1 V 80), ve joining genes (J 1 J 5), and one constant gene, C , in the undifferentiated cell (germ line). The nal light chain will be composed of the products of one variable gene, one joining gene, and the constant gene.

A computer-generated view of the interaction of an antigen-binding region of an immunoglobulin (green) with an antigen (purple: in this case, the hormone angiotensin II, composed of only eight amino acid residues). Note how the antigen ts into the variable end of the immunoglobulin, as an apple ts into a cupped hand. (a) Top view; (b) side view.

Figure 16.35 In order for V-J joining to take place (sitespeci c recombination), there must be signals at the V side and at the J side. One signal is a heptamer (seven base pairs) and a nonamer (nine base pairs) separated by twenty-three base pairs, and the other signal is the same heptamer and nonamer separated by twelve base pairs, in reverse orientation.

Immunogenetics
Two proteins, RAG1 and RAG2 (from recombination activating genes 1 and 2), form a recombinase enzyme capable of recognizing 12 23 signals and producing double-strand breaks in DNA at the junction of coding (V and J) regions and signal sequences (12 23 regions; g. 16.36). Recognition of the 12 23 signals is done with the help of HMG1 or HMG2 (high mobility group proteins 1 and 2), proteins that bind DNA and bend it, enhancing the activity of the RAG recombinase. The recombinase brings together one of the variable regions and one of the joining regions and links them in a process that also generates a circle of DNA with the intervening segments, which is then eliminated ( g. 16.36). The RAG recombinase nicks each DNA strand at its recombination signal sequence.Then by a transesteri cation (shifting a phosphodiester bond), the recombinase forms a hairpin and a blunt end, a double-strand break of the DNA ( g. 16.37).The remainder of the DNA processing is done with double-strand break repair enzymes that repair radiation-induced DNA damage ( g. 16.37; see chapter 12). The result is an eliminated circle of intervening genes and a chromosome with a V region adjacent to a new J region.
