Specific nuclear proteins interact with the Rous sarcoma virus internal enhancer and share a common element with the enhancer located in the long terminal repeat of the virus.
We have documented that the Rous sarcoma virus (RSV) internal enhancer functions in the nontransformed Baby Hamster Kidney (BHK) cell line. The sequences within this region were assayed for their ability to bind to specific factors present in BHK nuclear extracts using the gel retardation assay and DNAse I footprinting. At least two sequences within the internal enhancer which can specifically ...
متن کاملFoxA1 Translates Epigenetic Signatures into Enhancer-Driven Lineage-Specific Transcription
Complex organisms require tissue-specific transcriptional programs, yet little is known about how these are established. The transcription factor FoxA1 is thought to contribute to gene regulation through its ability to act as a pioneer factor binding to nucleosomal DNA. Through genome-wide positional analyses, we demonstrate that FoxA1 cell type-specific functions rely primarily on differential...
متن کاملPi, a pre-B-cell-specific enhancer element in the immunoglobulin heavy-chain enhancer.
We have identified a new immunoglobulin heavy-chain enhancer element, designated pi, between the microE2 and microE3 elements. The pi enhancer element is transcriptionally active primarily during early stages of B-cell development but becomes virtually inactive during B-cell maturation at about the stage of immunoglobulin kappa light-chain gene rearrangement. Mutational analysis suggests that t...
متن کاملp53 binds and represses the HBV enhancer: an adjacent enhancer element can reverse the transcription effect of p53.
The transcription program of the hepatitis B virus (HBV) genome is regulated by an enhancer element that binds multiple ubiquitous and liver-enriched transcription activators. HBV transcription and replication are repressed in the presence of p53. Here we describe a novel molecular mechanism that is responsible for this repression. The p53 protein binds to a defined region within the HBV enhanc...
متن کاملA Sox10 enhancer element common to the otic placode and neural crest is activated by tissue-specific paralogs.
The otic placode, a specialized region of ectoderm, gives rise to components of the inner ear and shares many characteristics with the neural crest, including expression of the key transcription factor Sox10. Here, we show that in avian embryos, a highly conserved cranial neural crest enhancer, Sox10E2, also controls the onset of Sox10 expression in the otic placode. Interestingly, we show that...
