Identification and regulation of tissue-specific cis-acting elements associated with the human AP-2alpha gene.
Mice lacking transcription factor AP-2alpha exhibit defects in the formation of the head, body wall, heart, neural tube, eye, and limbs, reflecting important sites of AP-2alpha expression in the developing embryo. AP-2alpha is also expressed in the postnatal mammary gland and has been linked to tumor progression and defects in growth regulation in the breast. We have used a transgenic mouse app...
متن کاملDevelopmental and spatial regulation of a Dictyostelium prespore gene: cis-acting elements and a cAMP-induced, developmentally regulated DNA binding activity.
Previously, 5' deletion analysis revealed three important upstream regions within the regulatory region of the cAMP-induced, prespore gene SP60 of D. discoidium, each of which contains a CA-rich sequence element (CAE: consensus CACACAYYYCACACAAA/T). In this study, we have made site-directed mutations within these CAEs and examined their effect on reporter gene activity (luciferase or lacZ). Poi...
متن کاملRegulation of Dictyostelium prestalk-specific gene expression by a SHAQKY family MYB transcription factor.
PstA and pstO cells are the two major populations in the prestalk region of the Dictyostelium slug and DIF-1 is a low molecular weight signalling molecule that selectively induces pstO cell-specific gene expression. The two cell types are defined by their differential use of spatially separated regions of the ecmA promoter. Additionally, there are anterior-like cells (ALCs) scattered throughout...
متن کاملIdentification and characterization of the cis-acting elements of the human CD155 gene core promoter.
The CD155 protein is the founding member of a new group of related molecules within the immunoglobulin superfamily sharing a V-C2-C2 domain structure and significant amino acid identity. We have recently isolated the promoter of the CD155 gene so that we may determine the transcription factors that regulate its expression and possibly gain insight into the cell biology of this gene. Here we rep...
متن کاملCis-acting elements regulating the placenta-specific promoter of the bovine Cyp19 gene.
Cyp19 encodes aromatase cytochrome P450, the key enzyme of oestrogen biosynthesis. In the bovine placenta, the majority of Cyp19 transcripts include a 5' untranslated region which is encoded by exon 1.1; this suggests that its 5'-flanking region is the predominant placental promoter. The aim of the present investigation was to examine the promoter activity of this region and to map cis-acting r...
