The TATA-binding protein (TBP) is a factor required for the transcription of all classes of eukaryotic genes. Here, we demonstrate that in the mouse the TBP-encoding gene (Tbp) resides next to the proteasomal subunit C5-encoding gene (Psmb1). The genes are located on mouse chromosome 17 in the t complex within the Hybrid sterility 1 (Hst1) region. We demonstrate that the homologous human genes (TBP AND PSMB1) are tightly linked on the long arm of chromosome 6, in a region syntenic with the proximal part of mouse chromosome 17. The mouse Tbp and Psmb1 and the human TBP and PSMB1 genes are transcribed in the opposite orientation. The TATA-binding protein and proteasomal subunit C5 genes are also linked on chromosome III of Caenorhabditis elegans, and together they are linked to other genes whose homologs map to human chromosome 6 and mouse chromosome 17. In the Drosophila genome, the housekeeping TATA-binding protein gene maps close to two other genes with homologs in the mammalian major histocompatibility complex. There thus exists conserved synteny of unrelated genes between mammals and invertebrates.

Four mouse genes, programmed cell death 2 (Pdcd2 or Rp8), brain protein 44-like (Brp441), bystin-like (Bysl), and uncoordinated-93-like (Unc931) genes were mapped to Chromosome (Chr) 17. The orthologs of these and other mouse Chr 17 genes are localized on Chr III of Caenorhabditis elegans, thus defining a syntenic group conserved between vertebrates and nonvertebrates. In human, mouse, and snake, the PDCD2-, and TATA-binding protein (TBP)-encoding genes are adjacent tail-to-tail. The TBP- and PDCD2-encoding genes are linked also in Drosophila, and, together with proteasomal subunit C5 gene, they are syntenic in human, mouse, C. elegans, and Schizosaccharomyces pombe. The orthologs of tightly linked C. elegans genes, coding for BRP44L and PDCD2, map to about 2-Mb interval on human region 6q27 and on mouse Chr 17. Hitherto, 13 members of synteny conserved between C. elegans and vertebrates have been detected, of which six are located on Drosophila Chr X. Such a distribution of transcription units is nonrandom and could indicate a long-range cis-acting relationship among the genes within the conserved syntenic group.

Three orthologous genes encoding programmed cell death 2 (PDCD2), TATA-binding protein (TBP), and proteasomal subunit C5 (PSMB1) proteins have been shown previously to be nonrandomly distributed in both mammalian and invertebrate genomes. Here we analyze a conserved synteny of the PDCD2, TBP, and PSMB1 orthologs in four nonmammalian vertebrates. Homologous genes of the chicken, zebrafish, fugu, and Tetraodon nigroviridis were identified. A chicken cosmid harboring the orthologs of these three genes was completely sequenced. The fish genes were analyzed in silico. In all seven vertebrates thus far investigated, the PDCD2 and TBP genes are located tail-to-tail. In six tested species but the zebrafish, the PSMB1 gene mapped head-to-head or in the close vicinity to the TBP, but even in the zebrafish, all three genes were syntenic. In contrast, a three times reused synteny breakpoint in the 5'-region from PDCD2 was detected. A comparative analysis revealed the distribution of putative matrix-attached regions (MARs), which may affect the synteny conservation.
