Evolutionary aspects of immunoglobulin heavy chain variable region (VH) gene subgroups.

We isolated and determined the sequences of two human germ-line heavy chain variable region (VH) genes and compared them with mouse VH genes. The results show that the human VHI subgroup is evolutionarily related to the mouse VHII subgroup. Evolutionary preservation of homologies in VH genes of the same subgroup includes not only the coding region but also intron size and homology in noncoding ...

Rearranged 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...

An 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...

Developmental 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...

Serological detection of variable region (Vh) subgroups of Ig heavy chains

Serological test systems were established for determining the heavy-chain variable region (Vh) subgroups of immunoglobulin heavy chains. Myeloma proteins with known Vh subgroups based on amino acid sequence were utilized as the primary basis of reference for analysis by hemagglutination and hemagglutination inhibition. Good agreement between the chemical and serological typing was obtained and ...
