    Notizen: Abstract. We isolated five different phage clones containing histone gene clusters with up to five H1 genes per phage clone from a Mytilus edulis genomic library. Among these H1 genes, nine gene types coding for five different H1 proteins have been identified. All H1 histone genes were located on repetitive restriction fragments with only slightly different sizes. The H1 coding regions show highly related sequences, suggesting that the multitude of H1 genes has evolved by gene duplication events. Core histone genes could not be found on these five Mytilus edulis genome fragments.

    Notizen: Abstract The sequences and organization of the histone genes in the histone gene cluster at the chromosomal marker D6S105 have been determined by analyzing the Centre d’Étude du Polymorphisme Humain yeast artificial chromosome (YAC) 964f1. The insert of the YAC was subcloned in cosmids. In the established contig of the histone-gene-containing cosmids, 16 histone genes and 2 pseudogenes were identified: one H1 gene (H1.5), five H2A genes, four H2B genes and one pseudogene of H2B, three H3 genes, and three H4 genes plus one H4 pseudogene. The cluster extends about 80 kb with a nonordered arrangement of the histone genes. The dinucleotide repeat polymorphic marker D6S105 was localized at the telomeric end of this histone gene cluster. Almost all human histone genes isolated until now have been localized within this histone gene cluster and within the previously described region of histone genes, about 2 Mb telomeric of the newly described cluster or in a small group of histone genes on chromosome 1. We therefore conclude that the data presented here complete the set of human histone genes. This now allows the general organization of the human histone gene complement to be outlined on the basis of a compilation of all known histone gene clusters and solitary histone genes.

    Notizen: Abstract A solitary histone H3 gene encoding a novel H3 protein sequence has been isolated. This H3 gene maps to chromosome 1 (1q42), whereas we have shown previously that the majority of the human histone genes form a large cluster on chromosome 6 (6p21.3). In addition, a small cluster has been described at 1q21. The clustered histone genes are expressed during the S-phase of the cell cycle, hence their definition as replication-dependent histone genes. In contrast, expression of replacement histone genes is essentially cell-cycle independent; they are solitary genes and map outside the major clusters. The newly described H3 gene maps outside all known histone gene clusters and varies by four amino acid residues from the consensus mammalian H3 structure. In contrast to other solitary histone genes, this human H3 gene shows the consensus promoter and 3′ flanking portions that are typical for replication-dependent genes.

    Notizen: A cluster of human histone genes was found on three overlapping clones isolated from cosmid and bacteriophage libraries. These three overlapping segments of the human genome comprise genes coding for H3.1, an H2A pseudogene, and an H2B.1 gene downstream of the previously characterized H1.2 gene. The cosmid clone covers 30 kb upstream of the H1.2 gene and overlaps with two phage clones covering the core histone genes and the pseudogene. The same arrangement of an H3 gene, an H2A pseudogene and an H2B gene downstream of an H1 gene has been described within a mouse histone gene cluster [Yang et al.: J Biol Chem 262:17118-17125, 1987; Gruber et al.: Gene 95:303-304, 1990].

    Notizen: The HFE (HLA-H) gene is a strong candidate gene for hereditary haemochromatosis and was localized on the short arm of chromosome 6 to 6p21.3-p22. In addition, the sequence of the homologous mouse and rat cDNA and a partial sequence from the mouse gene have been reported recently. In this report, we describe the location of the human and the mouse HFE (HLA-H) gene within the histone gene clusters on the human chromosome 6 and the mouse chromosome 13. Both the human and the murine gene were located on syntenic regions within the histone gene clusters in the vicinity of the histone H1t gene. The genomic sequence of the human HFE (HLA-H) gene and the 3′ portion of the homologous mouse gene were determined. Comparison of the genomic sequences from man and mouse and the cDNA sequence from rat shows significant similarities, also beyond the transcribed region of the mouse gene. J. Cell.
