Transcription factor that probably regulates the expression of the gene cluster that mediates the biosynthesis of notoamide, a fungal indole alkaloid that belongs to a family of natural products containing a characteristic bicyclo[2.2.2]diazaoctane core. Notoamides have been shown to exhibit antitumoral activities (PubMed:17304611). Notoamides A-C show moderate cytotoxicity against HeLa and L1210 cells with IC(50) values in the range of 22-52 mg/ml, but the IC(50) value of notoamide D is greater than 100 mg/ml (PubMed:17304611). Moreover, notoamide C induces G2/M-cell cycle arrest at a concentration of 6.3 mg/ml (PubMed:17304611).
