We have placed 7,600 cytogenetically defined landmarks on the draft sequence of the human genome to help with the characterization of genes altered by gross chromosomal aberrations that cause human disease. The landmarks are large-insert clones mapped to chromosome bands by fluorescence in situ hybridization. Each clone contains a sequence tag that is positioned on the genomic sequence. This genome-wide set of sequence-anchored clones allows structural and functional analyses of the genome. This resource represents the first comprehensive integration of cytogenetic, radiation hybrid, linkage and sequence maps of the human genome; provides an independent validation of the sequence map and framework for contig order and orientation; surveys the genome for large-scale duplications, which are likely to require special attention during sequence assembly; and allows a stringent assessment of sequence differences between the dark and light bands of chromosomes. It also provides insight into large-scale chromatin structure and the evolution of chromosomes and gene families and will accelerate our understanding of the molecular bases of human disease and cancer. 相似文献

Crystal structure of staphylococcal enterotoxin B, a superantigen. 总被引:39,自引:0,他引:39
The three-dimensional structure of staphylococcal enterotoxin B, which is both a toxin and a super-antigen, has been determined to a resolution of 2.5 A. The unusual main-chain fold containing two domains may represent a general motif adopted by all staphylococcal enterotoxins. The T-cell receptor binding site encompasses a shallow cavity formed by both domains. The MHCII molecule binds to an adjacent site. Another cavity with possible biological activity was also identified. 相似文献
