What's a GeneRIF?

Reactive oxygen species triggers unconventional secretion of antioxidants and Acb1.
Title: Reactive oxygen species triggers unconventional secretion of antioxidants and Acb1.
The major ESCRT-III subunit Snf7 localizes transiently to vesicles and tubules surrounded by a cup-shaped membrane and this was accelerated in vps4Delta cells, correlating with increased Acb1 secretion.
Title: ESCRT-III drives the final stages of CUPS maturation for unconventional protein secretion.
These experiments reveal a unique secretory pathway where autophagosomes containing Acb1 evade fusion with the vacuole to prevent cargo degradation.
Title: Unconventional secretion of Acb1 is mediated by autophagosomes.
study of the cardiolipin species profile in Saccharomyces cerevisiae by using depletion of the acyl-CoA-binding protein Acb1p
Title: Cardiolipin molecular species with shorter acyl chains accumulate in Saccharomyces cerevisiae mutants lacking the acyl coenzyme A-binding protein Acb1p: new insights into acyl chain remodeling of cardiolipin.
phospholipid biosynthesis gene expression is modulated either by the Acb1p-acyl-CoA ester complex directly or by its ability to donate acyl-CoA esters to utilizing systems.
Title: Transcriptional regulation of phospholipid biosynthesis is linked to fatty acid metabolism by an acyl-CoA-binding-protein-dependent mechanism in Saccharomyces cerevisiae.
