We describe a detailed genetic analysis of the DNA-binding regions in the HAP2/HAP3 CCAAT-binding heteromeric complex. The DNA-binding domain of HAP2 is shown to be a 21 residue region containing three critical histidines and three critical arginines. Mutation of an arginine at position 199 to leucine alters the DNA-binding specificity of the complex to(More)
The CCAAT-binding factor is a conserved heteromeric transcription factor that binds to CCAAT box-containing upstream activation sites (UASs) within the promoters of numerous eukaryotic genes. The CCAAT-binding factor of Saccharomyces cerevisiae activates the transcription of these genes in response to growth in a nonfermentable carbon source. Previous(More)
Abstract White spot syndrome virus (WSSV), Taura syndrome virus (TSV) and infectious hypodermal and haematopoietic necrosis virus (IHHNV) have been responsible for major pandemics affecting the shrimp farming industry. Shrimp samples were collected from eight farms in Hainan Province, China, during 2007 and analysed by polymerase chain reaction (PCR) or(More)
The present study was designed to determine whether the changes that occur during aging in the expression of the N-methyl-D-aspartate (NMDA) receptor and two NMDA receptor subunits, zeta1 and epsilon2, are a continuation of developmental processes and whether protein and mRNA expression patterns of the subunits are similar across the lifespan. The(More)
Chinese Erhualian pigs are known for prolificacy with distinct reproductive traits compared with Western commercial breeds. In this study, a four-generation intercross resource population was constructed using White Duroc boars and Chinese Erhualian sows as founder animals, and a total of 14 male reproductive traits were recorded in 411 F2/F3 boars(More)
Recently a strong positive association between schizophrenia and Notch4 has been reported. Both individual markers and haplotypes showed association with the disease, with five markers (three microsatellites and two SNPs) being tested. In order to test this finding we genotyped these markers in the Han Chinese population using a sample of 544 cases and 621(More)
D ata from twin, family, and adoption studies provide strong evidence that genetic factors play a major aetiological role in schizophrenia. By a series of linkage studies, chromosome 8p has been implicated as a region harbouring a schizophrenia susceptibility gene. 1–4 Recently, Stefansson and colleagues reported that neuregulin 1 (NRG1), located in(More)
There is accumulating evidence that the immune system can produce neuropeptides. In the light of these facts, we obtained direct evidences to prove that T lymphocytes also synthesize and secrete calcitonin gene-related peptide (CGRP), a neuropeptide localized within primary sensory nerves. By using CGRP specific RIA, CGRP-like immunoreactivity (LI) was(More)
We dissected the domain of HAP2 that mediates subunit association in the heteromeric CCAAT-binding complex, first by genetic mutational analysis and then by structural studies. The mutational data suggest that a very short region in HAP2 mediates protein-protein association and that the structure of this domain is likely to be an alpha-helix. The CD(More)
