SUT1 constitutive expression in aerobiosis suppressed the ts phenotype of the sec14-1 mutation, restored growth of the sec14-null mutant and corrected the translocation defect of the vacuolar carboxypeptidase Y. Therefore SUT1 was shown to be a novel potent sec14-1 suppressor. Further, the hypoxic gene CSR1 (YLR380W), a Sec14 homolog, was upregulated upon SUT1 constitutive expression. In addition, SUT1 effects on both sec14-1 suppression and on free sterol composition were abolished in a csr1-null background, showing that this gene acts downstream of SUT1.
