During seed germination, desiccation tolerance is lost in the radicle with progressing radicle protrusion and seedling establishment. This process is accompanied by comprehensive changes of the metabolome and proteome. Germination of Arabidopsis seeds was investigated over 72 h with special focus on...
Mitochondria possess elaborate machineries for the import of preproteins from the cytosol. Cytosolic factors like Hsp70 chaperones and their co-chaperones, the J-proteins, guide preproteins to the mitochondrial surface. The translocase of the mitochondrial outer membrane (TOM) forms the entry gate f...
Yeast strain lacking the two genes SSA1 and SSA2, which encode cytosolic chaperones, acquires thermotolerance as well as the mild heat-shocked wild-type yeast strain. Series containes 3 independent experiments.
The heat-shock response is a complex cellular program that induces major changes in protein translation, folding and degradation to alleviate toxicity caused by protein misfolding. While heat-shock has been widely used to study proteostasis, it remained unclear how misfolded proteins are targeted fo...
Elimination of misfolded proteins is crucial for proteostasis and to prevent proteinopathies. Nedd4/Rsp5 emerged as a major E3 ligase involved in multiple quality control pathways that target misfolded plasma membrane proteins, aggregated polypeptides, and cytosolic heat-induced misfolded proteins f...
Cytosolic iron-sulfur (Fe-S) cluster assembly (CIA) pathway delivers Fe-S clusters to nuclear and cytosolic Fe-S proteins involved in essential cellular functions. This delivery process is regulated by availability of iron and oxygen, but it remains unclear how CIA components orchestrate the cluster...
