What's a GeneRIF?

Transcription of CTR2 driven by the GPD promoter, which is not identical to the CTR2 promoter, affects degradation of the transcripts by nonsense-mediated mRNA decay pathway.
Title: Regulation of CTR2 mRNA by the nonsense-mediated mRNA decay pathway.
CTR2 plays a role in regulating the level of copper in the cytoplasm. Copper tolerance by the upf1Delta mutant is dependent on the presence of CTR2.
Title: Physiological basis of copper tolerance of Saccharomyces cerevisiae nonsense-mediated mRNA decay mutants.
These data suggest that Aft1p and Mac1p might corporately regulate transcription of CTR2.
Title: Metal-sensing transcription factors Mac1p and Aft1p coordinately regulate vacuolar copper transporter CTR2 in Saccharomyces cerevisiae.
these results suggest that Mac1p can activate the expression of vacuolar copper transporter Ctr2p in response to copper deficiency, resulting in yeast resistance to copper starvation.
Title: Low-affinity copper transporter CTR2 is regulated by copper-sensing transcription factor Mac1p in Saccharomyces cerevisiae.
Ctr2-1, a mutant form of Ctr2 that mislocalizes to the plasma membrane, requires the Fre1 plasma membrane metalloreductase for Cu(I) import.
Title: Identification of a vacuole-associated metalloreductase and its role in Ctr2-mediated intracellular copper mobilization.
demonstrate that copper transporter Ctr2 mobilizes vacuolar copper stores in a manner dependent on conserved amino acid residues
