Specific regulation of mRNA splicing in vitro by a peptide from HIV-1 Rev.
The Rev protein of HIV-1 regulates the synthesis of partially spliced forms of cytoplasmic viral mRNA by binding to a cis-acting RNA sequence, the Rev response element (RRE). We have investigated the regulation of splicing in vitro and have shown that Rev specifically inhibits splicing of pre-mRNAs containing an RRE by 3- to 4-fold. A synthetic peptide of 17 amino acids containing the RNA-bindi...
متن کاملThe HIV-1 Rev protein.
The nuclear export of intron-containing HIV-1 RNA is critically dependent on the activity of Rev, a virally encoded sequence-specific RNA-binding protein. Rev shuttles between the nucleus and the cytoplasm and harbors both a nuclear localization signal and a nuclear export signal. These essential peptide motifs have now been shown to function by accessing cellular signal-mediated pathways for n...
متن کاملRegulation of mRNA translation by signaling pathways.
mRNA translation is the most energy consuming process in the cell. In addition, it plays a pivotal role in the control of gene expression and is therefore tightly regulated. In response to various extracellular stimuli and intracellular cues, signaling pathways induce quantitative and qualitative changes in mRNA translation by modulating the phosphorylation status and thus the activity of compo...
متن کاملRegulation of mRNA translation.
The control of mRNA translation plays an important role in regulating gene expression in diverse situations. Nutrients, especially amino acids, regulate translation to control the expression of specific proteins including transcriptional activators and ribosomal proteins. Sequence elements in the 5'- or 3'-untranslated regions of mRNAs can control their translation. Hormones such as insulin act...
متن کاملThe Regulation of HIV-1 mRNA Biogenesis
The machinery regulating the transcription and processing of the human immunodeficiency virus type 1 (HIV-1) genome has been extensively studied for the past two decades, leading to the characterization of a complex set of interactions between viral and cellular factors. Our understanding of the basic molecular mechanisms regulating the expression of cellular genes has been greatly advanced by ...
