    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. The protease Kex1p appears to mediate HOClinduced lethality, since its absence enhances cell viability and decreases levels of ROS as well as formation of HOCl-modified epitopes upon challenge with lethal doses of HOCl.
      Title: The cell death protease Kex1p is essential for hypochlorite-induced apoptosis in yeast.
    2. Kex1 contributes also to the active cell death program induced by acetic acid stress or during chronological aging, suggesting that Kex1 plays a more general role in cellular suicide of yeast.
      Title: Kex1 protease is involved in yeast cell death induced by defective N-glycosylation, acetic acid, and chronological aging.
    3. Kex2 and Kex1 may promote cell fusion by proteolytically processing substrates that act in parallel to Prm1 as an alternative fusion machine, as cell wall components, or both.
      Title: The Golgi-resident protease Kex2 acts in conjunction with Prm1 to facilitate cell fusion during yeast mating.
