  • Title: Inactivation of rabbit immunoglobulin lambda chain variable region genes by the insertion of short interspersed elements of the C family.
    Author: Hayzer DJ, Jaton JC.
    Journal: Eur J Immunol; 1989 Sep; 19(9):1643-8. PubMed ID: 2507326.
    Abstract:
    Two rabbit germ-line genes encoding immunoglobulin lambda light chain V regions were cloned from a rabbit genomic liver DNA library and characterized. One, V lambda 1, is separated by at least 8 kb from any other V lambda gene. The second, V lamdba 4, forms part of a three-gene cluster with two functional V lambda genes recently reported. Both V lambda 1 and V lambda 4 have structural features rendering them pseudogenes. The coding regions have frame-shift mutations which would yield defective protein products; both genes are also interrupted by the insertions of short, interspersed repetitive elements of the C family. In the V lambda 1 gene, the 369-bp insert is located upstream of the gene between the putative TATA box and the leader exon, whereas in gene V lambda 4, the 360-bp insert interrupts the FR2 at codon 48c. In addition, the sequence of the complement-determining region 3 of gene V lambda 1 is very similar to the mouse DSP2.6 sequence.
