What's a GeneRIF?

Regulated targeting of the monotopic hairpin membrane protein Erg1 requires the GET pathway.
Title: Regulated targeting of the monotopic hairpin membrane protein Erg1 requires the GET pathway.
the spt23Delta mutant strain shows similar ERG1 expression to wild-type cells, while the mga2Delta/spt23Delta strain shows reduced ERG1 expression, comparable to the mga2Delta, suggesting that the role of regulation of ERG1 transcription is unique to Mga2p.

gene down-regulation increases the levels of the sterol precursor squalene twofold upon treatment with hydroge peroxide

Saccharomyces cerevisiae squalene epoxidase contains two highly conserved motifs, 1 and 2, of unknown function. Amino acid substitutions in both regions reduce enzyme activity and/or alter allylamine sensitivity.

NP_011691.1

EC 1.14.14.17

Squalene epoxidase; catalyzes epoxidation of squalene to 2,3-oxidosqualene; plays essential role in ergosterol-biosynthesis pathway and is specific target of antifungal drug terbinafine; directed to ER via guided entry of tail-anchored proteins (GET) pathway; degradation by ERAD triggered by membrane lipid saturation; human SQLE functionally complements the lethality of the erg1 null mutation
