    What's a GeneRIF?
    1. Alr1 is required for the up-regulation of the Mg(2+) content in polyamine-depleted cells
      Title: Elevation of cellular Mg(2+) levels by the Mg(2+) transporter, Alr1, supports growth of polyamine-deficient Saccharomyces cerevisiae cells.
    2. Superoxide is released at the level of Erv/ALR monomers and does not require the obligatory involvement of dimeric forms of these proteins as they reduce the superoxide ion and release up to ~30% of the oxygen.
      Title: Flavin-linked Erv-family sulfhydryl oxidases release superoxide anion during catalytic turnover.
    3. Data conclude that variation in Alr1 protein accumulation or location does not make a substantial contribution to its regulation by Mg supply, suggesting Alr1 activity is directly regulated via as yet unknown mechanisms.
      Title: Regulation of Alr1 Mg transporter activity by intracellular magnesium.
    4. High expression of inactive mutants inhibited the capability of wild-type Alr1 to transport magnesium, consistent with Alr1 forming homo-oligomers. The results confirm the classification of ALR1 as a member of the CorA family of magnesium transport genes.

    5. Alr1p and Alr2p are shown here to be present in the plasma membrane and shown to form homo-oligomers as well as hetero-oligomers; both the N-terminus and C-terminus of Alr1p and Alr2p are exposed to the inner side of the plasma membrane
