pubmed:abstractText |
We report the identification and purification of a yeast factor functionally homologous to the human upstream element factor (UEFh). Although the yeast protein (UEFy) has a higher molecular weight than the HeLa UEF (60 kD versus 45 kD) both have identical DNA-binding properties: the purified UEFy recognizes the Adenovirus 2 (Ad2) major late promoter upstream element (MLP-UE; from nucleotide -49 to -67) as well as the IVa2 upstream element (IVa2-UE; from nucleotide -98 to -122) with a higher affinity for the MLP-UE than for the IVa2-UE. Based on its DNA binding specificity, size and thermostability, the UEFy protein appears also similar or equivalent to the centromere binding protein CP1. In a competition assay with oligonucleotides containing the MLP-UE binding site, a drastic reduction of Ad2 MLP transcription was observed both in a HeLa and in a yeast cell free system, which was restored by addition of either the purified UEFh or UEFy proteins. We conclude that both UEFh and UEFy activate transcription from the Ad2 MLP upon binding to the upstream element, whatever is the in vitro cell-free system (yeast or HeLa). This indicate that some regulatory function represented by the upstream element and its cognate factor, is well conserved between human and yeast.
