    What's a GeneRIF?
    1. Saccharomyces cerevisiae can use two transport mechanisms to import lactic acid: a 'saturable' component of the transport, which requires the presence of a functional Jen1p transporter, and a Jen1p independent 'non-saturable' component.

    2. study demonstrated that monocarboxylate transporters Jen1 and Ady2 are modulators of lactic acid production
      Title: Lactic acid production in Saccharomyces cerevisiae is modulated by expression of the monocarboxylate transporters Jen1 and Ady2.

    4. Data show that casein kinase 1-dependent phosphorylation and HECT-ubiquitin ligase Rsp5-dependent ubiquitylation are required for Jen1 endocytosis.

    5. The presence of the JEN1(+391) transcript correlated with rapid glucose-triggered mRNA degradation of the JEN1(-51) transcript, whereas when the small transcript started at position +972, the JEN1(-51) mRNA turnover rate was unaffected.

    monocarboxylate/H+ symporter
    NP_012705.1
    • Monocarboxylate/proton symporter of the plasma membrane; transport activity is dependent on the pH gradient across the membrane; mediates high-affinity uptake of carbon sources lactate, pyuvate, and acetate, and also of the micronutrient selenite, whose structure mimics that of monocarboxylates; expression and localization are tightly regulated, with transcription repression, mRNA degradation, and protein endocytosis and degradation all occurring in the presence of glucose
