    Protein aggregates are associated with replicative aging without compromising protein quality control

    Juha Saarikangas, Yves Barral
    The aging lineage of budding yeast is differentiated by an early-appearing protein deposit that promotes protein quality control.

    A protein quality control pathway at the mitochondrial outer membrane

    Meredith B Metzger et al.
    Temperature-sensitive mitochondrial outer membrane proteins used as novel quality control substrates reveal a unique mitochondria-associated degradation pathway consisting of both cytosolic and mitochondrial ubiquitin-proteasome system machinery.

    Protein quality control in the nucleolus safeguards recovery of epigenetic regulators after heat shock

    Maria Azkanaz et al.
    Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.

    A conserved quality-control pathway that mediates degradation of unassembled ribosomal proteins

    Min-Kyung Sung et al.
    Tom1 is the ubiquitin ligase in yeast that anchors a protein quality control pathway that rapidly eliminates ribosomal proteins that fail to assemble into ribosomes.

    Quality control of transcription start site selection by nonsense-mediated-mRNA decay

    Christophe Malabat et al.
    RNA polymerase II generates numerous transcript isoforms, including transcripts initiating downstream of the START codon, that are efficiently degraded by the nonsense-mediated mRNA decay pathway.

    TAPBPR bridges UDP-glucose:glycoprotein glucosyltransferase 1 onto MHC class I to provide quality control in the antigen presentation pathway

    Andreas Neerincx et al.
    The recently discovered peptide editor TAPBPR binds to UDP-glucose:glycoprotein glucosyltransferase 1 to provide quality control in the antigen presentation pathway by facilitating the reglucosylation of the glycan on MHC class I molecules.
