MGA2
L000004181, YIR033W
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

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
Publication
The Rtt106 histone chaperone is functionally linked to transcription elongation and is involved in the regulation of spurious transcription from cryptic promoters in yeast.
Rtt106 is a histone chaperone that has been suggested to play a role in heterochromatin-mediated silencing in Saccharomyces cerevisiae. It interacts physically and functionally with the chromatin assembly factor-1 (CAF-1), which is associated with replication-coupled nucleosomal deposition. In this work, we have taken several approaches to study Rtt106 in greater detail and have identified a previously unknown function of Rtt106. ... [more]
