A specific mutant, upc2-1, of the predicted transcriptional activator UPC2 (YDR213w) has been recognized as a strain that allows a high level of aerobic sterol uptake. Another predicted transcriptional activator, the YLR228c gene product, is highly homologous to Upc2p. In fact, at the carboxy terminus 130 of the last 139 amino acids are similar between the two proteins. Since these proteins are very similar, the effect of mutations in the YLR228c open reading frame (ORF) was compared with like alterations in UPC2. First, the YLR228c ORF was insertionally inactivated and crossed with various UPC2 constructs. Deletion of YLR228c and UPC2 in combination resulted in nonviability, suggesting that the two proteins have some essential overlapping function. The upc2-1 point mutation responsible for aerobic sterol uptake was duplicated in the homologous carboxy region of the YLR228c ORF using site-directed mutagenesis. This mutation on a high-copy vector resulted in an increase in sterol uptake compared to an isogenic wild-type strain. The combination of both point mutations resulted in the greatest level of aerobic sterol uptake. When the YLR228c point mutation was expressed from a low-copy vector there was little if any effect on sterol uptake. Gas chromatographic analysis of the nonsaponifiable fractions of the various strains showed that the major sterol for all YLR228c and UPC2 combinations was ergosterol, the consensus yeast sterol.}, number={3}, journal={JOURNAL OF BACTERIOLOGY}, author={Shianna, KV and Dotson, WD and Tove, S and Parks, LW}, year={2001}, month={Feb}, pages={830–834} }

Growth of Phytophthora is often improved substantially when an exogenous source of sterol is provided. Additionally, sterols may be required for sexual and asexual sporulation in Phytophthora. Our research has been focused on identifying and characterizing the immediate physiological effects following sterol addition to cultures of P. parasitica. Through gas chromatographic analysis of extracts from P. parasitica cultures that were fed various sterols, we have obtained evidence for sterol C5 desaturase and delta7 reductase activities in this organism. Zoo blots were probed with DNA sequences encoding these enzymes, from Saccharomyces cerevisiae and Arabidopsis thaliana. Hybridization of a S. cerevisiae ERG3 probe to P. parasitica DNA was observed, implicating sequence similarity between the sterol C5 desaturase encoding genes. Differential display experiments, using RNA from P. parasitica, have demonstrated a pattern of altered gene expression between cultures grown in the presence and absence of sitosterol. Characterization of sterol-related metabolic effects and sterol functions in Phytophthora should lead to improved measures for control of this important group of plant pathogens.}, number={3}, journal={LIPIDS}, author={Dotson, WD and Tove, SR and Parks, LW}, year={2000}, month={Mar}, pages={243–247} }

In addition to accumulating vesicles, the mutants do not esterify free sterol on rich media at the restrictive temperature. It is the high level of inositol in the media that causes this condition in the yeast Saccharomyces cerevisiae, not a defective steryl ester synthase or lack of substrates. When strains containing the sec1 or sec5 mutation were transformed separately with a plasmid carrying SEC1 and SEC5, the esterification and secretory defects were alleviated. Double mutants containing sec6, sec14 or sec18 with either a sec1 or sec5 mutation have normal esterification levels. Strains with suppressor mutations were isolated that grew at 37 degrees C, esterified sterols and had diminished accumulation of vesicles, when grown at the restrictive temperature on defined media with additional inositol. Electron microscopy was used to examine vesicle accumulation, the number of lipid droplets, and to further characterize the esterification defect. When grown at 37 degrees C on defined medium, the strains with sec5 or sec1 accumulated the usual secretory vesicles, but when grown under similar conditions with elevated levels of inositol, accumulated an additional vesicular-like body.}, number={5}, journal={Yeast}, author={Tomeo, M.
