| pubmed-article:12381299 | pubmed:abstractText | Cis-acting CCAAT elements are found frequently in eukaryotic promoter regions. Many of the genes containing such elements in their promoters are regulated by a conserved multimeric CCAAT-binding complex. In the fungus Emericella (Aspergillus) nidulans, this complex was designated AnCF (A.nidulans CCAAT-binding factor). AnCF regulates several genes, including the penicillin biosynthesis genes ipnA and aatA. Since it is estimated that the CCAAT-binding complex regulates more than 200 genes, an important question concerns the regulation mechanism that allows so many genes to be regulated by a single complex in a gene-specific manner. One of the answers to this question appears to lie in the interaction of AnCF with other transcription factors. Here, a novel transcription factor designated AnBH1 was isolated. The corresponding anbH1 gene was cloned and found to be located on chromosome IV. The deduced AnBH1 protein belongs to the family of basic-region helix-loop-helix (bHLH) transcription factors. AnBH1 binds in vitro as a homodimer to an, not previously described, asymmetric E-box within the aatA promoter that overlaps with the AnCF-binding site. This is the first report demonstrating that the CCAAT-binding complex and a bHLH transcription factor bind to overlapping sites. Since deletion of anbH1 appears to be lethal, the anbH1 gene was replaced by a regulatable alcAp-anbH1 gene fusion. The analysis of aatAp-lacZ expression in such a strain indicated that AnBH1 acts as a repressor of aatA gene expression and therefore counteracts the positive action of AnCF. | lld:pubmed |
