APP1 transcription is regulated by inositol-phosphorylceramide synthase 1-diacylglycerol pathway and is controlled by ATF2 transcription factor in Cryptococcus neoformans.
Mare L, Iatta R, Montagna MT, Luberto C, Del Poeta M. Mare L, et al. J Biol Chem. 2005 Oct 28;280(43):36055-64. doi: 10.1074/jbc.M507285200. Epub 2005 Aug 29. J Biol Chem. 2005. PMID: 16129666
To this end, the APP1 promoter was fused to the firefly luciferase gene in the C. neofor-mans GAL7:IPC1 strain, in which the Ipc1 expression can be modulated, and found that the luciferase activity was indeed regulated when Ipc1 was modulated. ...These studies provide nove …
