Nucleotide sequences for two immunoglobulin heavy chain variable region (VH) genes and one pseudogene in the goldfish (Carassius auratus) and the family relationships and distribution of these genes in individual fish are presented. Comparison of the nucleotide and inferred amino acid sequences of goldfish and other vertebrate VH genes indicates that goldfish VH genes show the major VH gene reg...

We previously detected mRNAs in a number of human T cell lines with a probe from within the Ig VH gene locus. We now show these mRNAs consist of Ig VH genes expressed in T cells. In one human T cell line, two RNA species have been studied and found to come from transcripts of unrearranged VH segments in which the leader exon, normally associated with VH transcripts in B cells, is replaced by a ...

To define members of previously unknown VH gene families, a channel catfish immunoglobulin heavy chain cDNA library was constructed and screened with probes specific for the seven known catfish VH families. Reiterative screening and sequence studies defined six new VH families, designated VH8-VH13, which brings the total number of VH families in the catfish to 13. This is the highest number of ...

An efficient method for extracting volumetric data from simulations is developed. The method is illustrated using a recent atomic-level molecular dynamics simulation of L alpha phase 1,2-dipalmitoyl-sn-glycero-3-phosphocholine bilayer. Results from this simulation are obtained for the volumes of water (VW), lipid (V1), chain methylenes (V2), chain terminal methyls (V3), and lipid headgroups (VH...

Vibrio harveyi NADPH:FMN oxidoreductase P (FRP(Vh)) is a homodimeric enzyme having a bound FMN per enzyme monomer. The bound FMN functions as a cofactor of FRP(Vh) in transferring reducing equivalents from NADPH to a flavin substrate in the absence of V. harveyi luciferase but as a substrate for FRP(Vh) in the luciferase-coupled bioluminescent reaction. As part of an integral plan to elucidate ...

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 ...

A set of six mutants of the levan binding single-chain Fv (scFv) fragment A48 (ABPC48), which have the identical light chain but differ gradually in the stability of the heavy chain, was generated. This was achieved by introducing one or both of the stabilizing mutations H-K66R and H-N52S into the VH domain of the A48 wild-type protein, which is naturally missing the conserved disulfide bridge ...

Human responses to an interaction with a Virtual Human (VH) can be influenced by both external factors such as technologyrelated limitations, and internal factors such as individual differences in personality. While the impacts of external factors have been studied widely, and are typically controlled for in application scenarios, less attention has been devoted to the impacts of internal facto...

AT11-2, an Abelson virus-transformed cell line has DJH complexes on both chromosomes and is able to form functional variable region genes by the joins of VH genes to the DJH complexes during culture. Therefore we examined which VH gene family was used in functional VH to DJH recombinations in AT11-2. Surprisingly, of 32 independent functional VH to DJH recombinational events in AT11-2, 31 event...

Using amplified cDNA and genomic libraries, we have analyzed the VH gene repertoire of pre-B cells and various B cell subsets of conventional mice at the level of VH genes belonging to the J558 VH gene family. The sequence data were evaluated on the basis of a newly established list of 67 J558 VH genes that comprise approximately two-thirds of the J558 VH genes of the murine IgHb haplotype. The...
