Abstract
The linking of the human VK and JKCK gene regions (abbreviations in ref. 1) by chromosomal walking is reported. Hybridization experiments with the DNA of a somatic cell hybrid containing the region between JKCK and the telomer show that none of the major VK gene clusters is located downstream of CK. The distance between the VK and JK genes was found to be 23 kb. The JK proximal VK gene is the B3 gene which is the only representative of subgroup IV in the genome. This gene and the neighbouring B2 gene (accompanying paper) are arranged in opposite orientation to JKCK and can therefore rearrange only by an inversion mechanism. This finding is used, together with previous data, to delineate the rearrangement processes in the Burkitt lymphoma derived cell line BL21 as comprising an inversion in the first and a deletion in the second step.Keywords
