| Standard Name | MGA2 |
|---|---|
| Systematic Name | YIR033W |
| Feature Type | ORF, Verified |
| Description | ER membrane protein involved in regulation of OLE1 transcription; inactive ER form dimerizes and one subunit is then activated by ubiquitin/proteasome-dependent processing followed by nuclear targeting; MGA2 has a paralog, SPT23, that arose from the whole genome duplication (1, 2, 3) |
| Name Description | Multicopy suppressor of GAm1 (snf2) 4 |
