GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. The product distribution in the strains indicated that the energy barrier could be the reason that different metal ion-assisted electrophilic attacks initiated carbocation formation.
    Title: ERG9 and COQ1 disruption reveals isoprenoids biosynthesis is closely related to mitochondrial function in Saccharomyces cerevisiae.
  2. Coq1 is functional when expressed alone in E. coli and in budding yeast, but is only functional as a partner with Dps1 in fission yeast.
