Protein kinase A regulates RNA polymerase III transcription through the nuclear localization of Maf1
Maf1 is an essential and specific mediator of transcriptional repression in the RNA polymerase (pol) III system. Maf1-dependent repression occurs in response to a wide range of conditions, suggestingExpand
Two Steps in Maf1-dependent Repression of Transcription by RNA Polymerase III*
In Saccharomyces cerevisiae, Maf1 is essential for mediating the repression of transcription by RNA polymerase (pol) III in response to diverse cellular conditions. These conditions activate distinctExpand
Regulation of RNA Polymerase III Transcription Involves SCH9-dependent and SCH9-independent Branches of the Target of Rapamycin (TOR) Pathway*
Maf1 is a conserved repressor of transcription that functions at the downstream end of multiple nutrient and stress signaling pathways. How these different signaling pathways converge on Maf1 is notExpand
Chemical activation of Sir2-dependent silencing by relief of nicotinamide inhibition.
Sir2 is a nicotinamide adenine dinucleotide (NAD+)-dependent protein deacetylase involved in gene silencing and longevity. Cellular stresses affect Sir2 activity, but the mechanisms of Sir2Expand
Repression of Ribosome and tRNA Synthesis in Secretion-Defective Cells Is Signaled by a Novel Branch of the Cell Integrity Pathway
ABSTRACT The transcription of ribosomal DNA, ribosomal protein (RP) genes, and 5S and tRNA genes by RNA polymerases (Pols) I, II, and III, respectively, is rapidly and coordinately repressed uponExpand
TOR signaling regulates ribosome and tRNA synthesis via LAMMER/Clk and GSK-3 family kinases.
Target of rapamycin (TOR)-dependent signaling and the control of cell growth is deregulated in many cancers. However, the signaling molecules downstream of TOR that coordinately regulate theExpand
Kar2p availability defines distinct forms of endoplasmic reticulum stress in living cells
The endoplasmic reticulum (ER) unfolded protein response (UPR) is correlated with changes in unfolded secretory levels. A novel fluorescence biosensor now reports changes in the unfolded proteinExpand
Nhp6, an HMG1 protein, functions in SNR6 transcription by RNA polymerase III in S. cerevisiae.
Nhp6A and Nhp6B are HMG1-like proteins required for the growth of S. cerevisiae at elevated temperatures. We show that the conditional lethality of an nhp6 strain results from defective transcriptionExpand
Loss of the RNA polymerase III repressor MAF1 confers obesity resistance.
MAF1 is a global repressor of RNA polymerase III transcription that regulates the expression of highly abundant noncoding RNAs in response to nutrient availability and cellular stress. Thus, MAF1Expand
SCS3 and YFT2 Link Transcription of Phospholipid Biosynthetic Genes to ER Stress and the UPR
The ability to store nutrients in lipid droplets (LDs) is an ancient function that provides the primary source of metabolic energy during periods of nutrient insufficiency and between meals. The FatExpand
