Abstract

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.
