Cooperativity of glucocorticoid response elements located far upstream of the tyrosine aminotransferase gene.
Two glucocorticoid response elements (GREs) located 2.5 kb upstream of the transcription initiation site of the tyrosine aminotransferase gene were identified by gene transfer experiments and shown to bind to purified glucocorticoid receptor. Although the proximal GRE has no inherent capacity by itself to stimulate transcription, when present in conjunction with the distal GRE, this element syn...
متن کاملChicken ovalbumin upstream promoter-transcription factor interacts with estrogen receptor, binds to estrogen response elements and half-sites, and inhibits estrogen-induced gene expression.
Chicken ovalbumin upstream promoter-transcription factor (COUP-TF) was identified as a low abundance protein in bovine uterus that co-purified with estrogen receptor (ER) in a ligand-independent manner and was separated from the ER by its lower retention on estrogen response element (ERE)-Sepharose. In gel mobility shift assays, COUP-TF bound as an apparent dimer to ERE and ERE half-sites. COUP...
متن کاملControl elements targeting Tgfb3 expression to the palatal epithelium are located intergenically and in introns of the upstream Ift43 gene
Tgfb3 is strongly and specifically expressed in the epithelial tips of pre-fusion palatal shelves where it plays a critical non-redundant role in palatal fusion in both medial edge epithelial (MEE) cells and in a thin layer of flattened peridermal cells that covers the MEE. It is not known how Tgfb3 expression is regulated in these specific cell types. Using comparative genomics and transgenic ...
متن کاملTwo upstream elements activate transcription of a major histocompatibility complex class I gene in vitro.
Expression of major histocompatibility complex (MHC) class I genes exhibits unique tissue and developmental specificity. In an effort to study molecular mechanisms of MHC class I gene regulation, an in vitro transcription system has been established. In B cell nuclear extracts a template DNA containing the mouse H-2Ld promoter sequence accurately directed RNA polymerase II-dependent transcripti...
متن کاملConserved sequence motifs upstream from the co-ordinately expressed vitellogenin and apoVLDLII genes of chicken.
The vitellogenin and apoVLDLII yolk protein genes of chicken are transcribed in the liver upon estrogenization. To get information on putative regulatory elements, we compared more than 2 kb of their 5' flanking DNA sequences. Common sequence motifs were found in regions exhibiting estrogen-induced changes in chromatin structure. Stretches of alternating pyrimidines and purines of about 30-nucl...
