We recently identified and cloned a novel human gene, Che-1, whose product interacts with both RNA polymerase II and the retinoblastoma gene product (Rb). Furthermore, we found that Che-1 overexpression counteracts the growth inhibitory effects of Rb, regulating in such way both transcription and cell proliferation. In this paper, we describe the genomic organization of the mouse orthologous Che-1 gene and its promoter region. The promoter is TATA less and presents several potential transcription factor-binding motifs. Importantly, we showed that Che-1 expression is regulated by a negative feedback mechanism, in which this protein is present on its own promoter repressing transcription. (C) 2003 Elsevier B.V.
