A Novel Nuclear Import Pathway for the Transcription Factor TFIIS
We have identified a novel pathway for protein import into the nucleus. We have shown that the previously identified but uncharacterized yeast protein Nmd5p functions as a karyopherin. It was therefore designated Kap119p (karyopherin with Mr of 119 kD). We localized Kap119p to both the nucleus and the cytoplasm. We identified the transcription elongation factor TFIIS as its major cognate import...
متن کاملA Novel Receptor-Mediated Nuclear Protein Import Pathway
Targeting of most nuclear proteins to the cell nucleus is initiated by interaction between the classical nuclear localization signals (NLSs) contained within them and the importin NLS receptor complex. We have recently delineated a novel 38 amino acid transport signal in the hnRNP A1 protein, termed M9, which confers bidirectional transport across the nuclear envelope. We show here that M9-medi...
متن کاملEndothelial nuclear lamina is not required for glucocorticoid receptor nuclear import but does affect receptor-mediated transcription activation.
The lamina serves to maintain the nuclear structure and stiffness while acting as a scaffold for heterochromatin and many transcriptional proteins. Its role in endothelial mechanotransduction, specifically how nuclear mechanics impact gene regulation under shear stress, is not fully understood. In this study, we successfully silenced lamin A/C in bovine aortic endothelial cells to determine its...
متن کاملThe nuclear receptor transcription factor, retinoid-related orphan receptor β, regulates retinal progenitor proliferation
We examined the role of retinoid-related orphan receptor (ROR)beta, a member of the nuclear receptor family of transcription factors, in retinal neurogenesis. In situ hybridization studies showed that RORbeta is expressed in retinal progenitor cells in the embryonic rat retina. Further studies demonstrated that RORbeta colocalizes with Chx10, a transcription factor thought to influence retinal ...
متن کاملDeoxyribonucleic acid response element-dependent regulation of transcription by orphan nuclear receptor estrogen receptor-related receptor gamma.
The estrogen receptor-related receptor gamma (ERR gamma/ERR3/NR3B3) is the newest member of the ERR subfamily that also includes ERR alpha and ERR beta. All three isoforms share a high degree of amino acid identity especially in the DNA binding domain. ERR gamma is a constitutively active transcriptional activator that regulates reporter elements driven by steroidogenic factor 1 response elemen...
