Membrane biology: Membrane-regulated transcription
The activation of membrane-bound transcription factors involves release from the membrane by proteolysis. Recent studies show that, for some proteins, cleavage is performed by the proteasome, whereas others require specific proteases.
متن کاملSREBPs: sterol-regulated transcription factors.
Studies of the feedback regulation of cholesterol synthesis in animals have led to the identification of a unique family of membrane-bound transcription factors, sterol regulatory element binding proteins (SREBPs) (Brown and Goldstein, 1997). In the presence of cholesterol, SREBPs are sequestered in the endoplasmic reticulum (ER). In the absence of a sterol signal, however, SREBPs undergo speci...
متن کاملMechanisms of Glucocorticoid-Regulated Gene Transcription.
One fascinating aspect of glucocorticoid signaling is their broad range of physiological and pharmacological effects. These effects are at least in part a consequence of transcriptional regulation by the glucocorticoid receptor (GR). Activation of GR by glucocorticoids results in tissue-specific changes in gene expression levels with some genes being activated whereas others are repressed. This...
متن کاملMIRTFnet: Analysis of miRNA Regulated Transcription Factors
BACKGROUND Several expression datasets of miRNA transfection experiments are available to analyze the regulatory mechanisms downstream of miRNA effects. The miRNA induced regulatory effects can be propagated via transcription factors (TFs). We propose the method MIRTFnet to identify miRNA controlled TFs as active regulators if their downstream target genes are differentially expressed. METHOD...
