The Complete Nucleotide Sequence of the Human Immunoglobulin Heavy Chain Variable Region Locus
The complete nucleotide sequence of the 957-kb DNA of the human immunoglobulin heavy chain variable (VH) region locus was determined and 43 novel VH segments were identified. The region contains 123 VH segments classifiable into seven different families, of which 79 are pseudogenes. Of the 44 VH segments with an open reading frame, 39 are expressed as heavy chain proteins and 1 as mRNA, while t...
متن کاملDevelopmental progression of equine immunoglobulin heavy chain variable region diversity.
Humoral immunity is a critical component of the immune system that is established during fetal life and expands upon exposure to pathogens. The extensive humoral immune response repertoire is generated in large part via immunoglobulin (Ig) heavy chain variable region diversity. The horse is a useful model to study the development of humoral diversity because the placenta does not transfer mater...
متن کامل202 Immunoglobulin Heavy Chain Diversity Dna Segments
Complete, active, immunoglobulin variable (V) 1 genes are generated by somatic rearrangement of DNA sequences during the differentiation of lymphocyte precursor cells (1, 2). In the mouse, the conventionally defined V region of the light chains, both and ~¢ types, consists of two DNA segments: VL and Je, which are separate in the germline genome. The two DNA segments are joined at the 3' end of...
متن کاملAn immunoglobulin heavy chain variable region gene is generated from three segments of DNA: VH, D and JH.
We have determined the sequences of separate germline genetic elements which encode two parts of a mouse immunglobulin heavy chain variable region. These elements, termed gene segments, are heavy chain counterparts of the variable (V) and joining (J) gene segments of immunoglobulin light chains. The VH gene segment encodes amino acids 1-101 and the JH gene segment encodes amino acids 107-123 of...
متن کاملRearranged immunoglobulin heavy chain variable region (VH) pseudogene that deletes the second complementarity-determining region.
We have cloned two rearranged heavy chain variable region (VH) genes from the IgG-producing human cell line CESS. The VH gene, which is linked to the mu chain constant region (C mu) gene, has two deletions at residues 45-62 and 82A-90, the former of which corresponds closely to the second complementarity-determining region (CDR2). These results could indicate that translocation of CDR2 occurred...
