CC   -!- FUNCTION: Part of the NCT transcriptional regulatory complex that acts
CC       as a key regulator of ergosterol biosynthesis and the azole exporter
CC       cdr1B (PubMed:31969561). The NCT complex binds the promoters of genes
CC       linked to azole susceptibility, and especially represses the expression
CC       of cdr1B transporter (PubMed:31969561). {ECO:0000269|PubMed:31969561}.
CC   -!- SUBUNIT: Forms the NCT transcriptional regulatory complex with nctA and
CC       mot1. {ECO:0000269|PubMed:31969561}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305|PubMed:31969561}.
CC   -!- DISRUPTION PHENOTYPE: Leads to a multidrug-resistance phenotype,
CC       including the azoles (itraconazole, voriconazole and posaconazole), as
CC       well as the salvage therapeutic amphotericin B and terbinafine, an
CC       agent used in the treatment of chronic and allergic disease
CC       (PubMed:31969561). Leads also to transcriptional derepression of cdr1B
CC       and its over-production (PubMed:31969561). Results also in a notable
CC       increase in the immunogenic properties of Aspergillus fumigatus, but
CC       does not result in loss of virulence (PubMed:31969561).
CC       {ECO:0000269|PubMed:31969561}.
CC   -!- SIMILARITY: Belongs to the NC2 beta/DR1 family. {ECO:0000305}.
