| Disruption Phenotype | Accumulates 20% of ergosterol of wild type. {ECO:0000269|PubMed:9468503}. |
| Function | This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5. Involved in ergosterol biosynthesis. Has NADPH-dependent ferrireductase activity on the plasma membrane. {ECO:0000269|PubMed:11485306, ECO:0000269|PubMed:1730736, ECO:0000269|PubMed:9368374, ECO:0000269|PubMed:9468503}. |
| Induction | By galactose and on the plasma membrane by iron or copper deficiency. Repressed by glucose. {ECO:0000269|PubMed:9368374}. |
| Miscellaneous | Present with 46600 molecules/cell in log phase SD medium. {ECO:0000269|PubMed:14562106}. |
| Ptm | Phosphorylated by the cyclin-CDK PCL1-PHO85. {ECO:0000269|PubMed:15082539}. |
| Similarity | Contains 1 FAD-binding FR-type domain. {ECO:0000255|PROSITE-ProRule:PRU00716}. |
