    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. We conclude that specific J-proteins and Hsp100 chaperones act together with Hsp70 to recognize and deliver DXS to either reactivation (via ClpB3) or removal (via ClpC1) depending on the physiological status of the plastid. [J20]
      Title: Specific Hsp100 Chaperones Determine the Fate of the First Enzyme of the Plastidial Isoprenoid Pathway for Either Refolding or Degradation by the Stromal Clp Protease in Arabidopsis.
    2. J20 is a J-protein that delivers deoxyxylulose-5-phosphate synthase to plastidial Hsp70 chaperones.
      Title: Arabidopsis J-protein J20 delivers the first enzyme of the plastidial isoprenoid pathway to protein quality control.
    3. A lack of AtJ8, AtJ11, or AtJ20 triggers a global stress response and therefore confers the plants greater tolerance to oxidative stress.
