Complete physical map of the human immunoglobulin heavy chain constant region gene complex.
We have found by pulsed-field gel electrophoresis that the human immunoglobulin heavy chain constant region gene complex maps entirely to a 350-kilobase (kb) Mlu I fragment. The enzyme Eag I was used with pulsed-field gel electrophoresis alone and in double digests with Spe I to map the region. C gamma 3, of the C gamma 3-C gamma 1-C psi epsilon 1-C alpha 1 cluster, maps 60 kb to the 3' side of...
متن کاملMultiple gene deletions within the human immunoglobulin heavy-chain cluster.
Two subjects, of 11,000 healthy individuals screened, were found to be missing three and four immunoglobulin isotypes, respectively (IgA1, IgG2, and IgG4; IgA1, IgG2, IgG4, and IgE), and have been analyzed at the DNA level by means of Southern blotting and Ig heavy-chain-specific probes. A broad deletion within the heavy-chain constant region (C) gene cluster was found on chromosome 14 of both ...

15 صفحه اولRegulation of immunoglobulin heavy-chain gene rearrangements.
Regulated assembly of antigen receptor gene segments to produce functional genes is a hallmark of B- and T-lymphocyte development. The immunoglobulin heavy-chain (IgH) and T-cell receptor beta-chain genes rearrange first in B and T lineages, respectively. Both loci require two recombination events to assemble functional genes; D-to-J recombination occurs first followed by V-to-DJ recombination....
متن کاملPhysical mapping of the bovine immunoglobulin heavy chain constant region gene locus.
Bovine antibodies have recently attracted increasing attention, as they have been shown to exhibit prophylactic and therapeutic properties in selected infectious diseases in humans. In the present study, we have isolated bacterial artificial chromosomes and cosmid clones containing the bovine JH, mu, delta, gamma 1, gamma 2, gamma 3, epsilon, and alpha genes, which allowed us to make a contig o...
