Recombination between antibody heavy chain variable-region genes: evidence for gene conversion.
The murine hybridoma line B1-8.delta 1 secretes monoclonal IgD lambda 1 antibodies specific for the hapten (4-hydroxy-3-nitrophenyl)acetyl (NP). The variable (V) region of these antibodies is defined by a characteristic pattern of idiotopes. A spontaneous V-region variant (B1-8.V1) with altered idiotope pattern was selected. The structural variation is confined to the V region of the heavy chai...
متن کاملEvidence for gene conversion among immunoglobulin heavy chain variable region genes
We have previously reported that the VH region amino acid sequence of a phosphocholine (PC)-binding hybridoma antibody of CBA/J origin, HP101 6G6 (6G6), differs extensively from the VH regions of other PC-binding antibodies. The sequence of 6G6 VH appears to be derived from a gene homologous to the BALB/c V11 gene, a member of the PC VH (T15 VH) gene family not normally used to encode PC-bindin...
متن کاملHuman heavy chain variable region gene diversity, organization, and expression.
Elucidation of the cellular and molecular mechanisms which determine the expressed antibody repertoire remains a major challenge in immunology. Knowledge of V gene diversity, organization, and expression is important to an understanding of the formation of the antibody repertoire in normal as well as diseased states. In the last few years, great advances have been made in our understanding of t...
متن کاملPolymorphisms of a human variable heavy chain gene show linkage with constant heavy chain genes.
In this study, restriction fragment length polymorphisms (RFLPs) were identified with an immunoglobulin variable heavy chain region (Ig VH) probe and the inheritance of the polymorphisms was analyzed in families. Linkage within the VHII gene cluster and between the VHII and Ig CH genes was investigated by lod (logarithm of odds) score analysis. In addition, the position of the VHII genes was de...
متن کاملStructure and multiplicity of genes for the human immunoglobulin heavy chain variable region.
Several genes for the variable region of immunoglobulin heavy chains (VH genes) have been isolated from human fetal liver DNA by using a cDNA plasmid probe containing a mouse VH sequence. The detectable VH genes are separated by 12-16 kilobases of DNA, and hybridization experiments show about 23 hybridizing VH genes in DNA of three different individuals. The complete nucleotide sequence of one ...
