Transcription factor that acts as a transcriptional activator of a number of genes encoding proteasomal subunits. Plays a role in ergosterol and plasma membrane homeostasis, and subsequent azole resistance. Regulates the expression of 212 genes, activating 80 genes and repressing, likely in an indirect fashion, 132 genes. Targets comprise several proteasome and ergosterol biosynthesis genes, including ERG1, ERG2, ERG3, and ERG11. Directly regulates ERG11 expression through the 3'-TTGCAAA-5' binding motif
