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 [Source:SGD;Acc:S000001472]
Chromosome IX: 416,124-419,465 forward strand.
R64-1-1:BK006942.2
This gene has 1 transcript (splice variant) and 342 orthologues.
