    What's a GeneRIF?
    1. Gyp1 acts as a Ypt1 GTPase-activating protein (GAP) for selective autophagic variants, such as the Cvt pathway or the selective autophagic degradation of mitochondria (mitophagy). Gyp1 regulates the dynamic disassembly of the conserved Ypt1-Atg1 complex. Thereby, Gyp1 sets the stage for efficient Atg14 recruitment, and facilitates the critical step from nucleation to elongation of the phagophore.
      Title: Gyp1 has a dual function as Ypt1 GAP and interaction partner of Atg8 in selective autophagy.
    2. Ypt1p regulates the flow of traffic into the cis and trans side of the Golgi via multiple effectors.
      Title: Establishing a role for the GTPase Ypt1p at the late Golgi.
    3. Data show that Gyp1p, a GAP for Ypt1p, specifically interacts with Ypt32p, and that this interaction is important for the localization and stability of Gyp1p.
