Protein Quality Control at the Mitochondrial Surface
Mitochondria contain two membranes, the outer and inner membrane. The outer membrane fulfills crucial functions for the communication of mitochondria with the cellular environment like exchange of lipids via organelle contact sites, the transport of ...

Methionine Redox Homeostasis in Protein Quality Control
Bacteria live in different environments and are subject to a wide variety of fluctuating conditions. During evolution, they acquired sophisticated systems dedicated to maintaining protein structure and function, especially during oxidative stress.

Protein quality control meets transcriptome remodeling under stress
To tolerate and recover from genotoxic stress cells must coordinate a range of stress response activities including cell cycle arrest, DNA repair, and remodeling of the transcriptome and proteome.

Quality control of integral membrane proteins
Integral membrane proteins (IMPs) are essential components of the plasma and organellar membranes of the eukaryotic cell. Non-native IMPs, which can arise as a result of mutations, errors during biosynthesis or cellular stress, can disrupt these membranes and potentially lead to cell death.

Cellular Strategies of Protein Quality Control [PDF]
Eukaryotic cells must contend with a continuous stream of misfolded proteins that compromise the cellular protein homeostasis balance and jeopardize cell viability. An elaborate network of molecular chaperones and protein degradation factors continually monitor and maintain the integrity of the proteome. Cellular protein quality control relies on three

Rapid online buffer exchange for screening of proteins, protein complexes and cell lysates by native mass spectrometry [PDF]
It is important to assess the identity and purity of proteins and protein complexes during and after protein purification to ensure that samples are of sufficient quality for further biochemical and structural characterization, as well as for use in ...

TSPO interacts with VDAC1 and triggers a ROS-mediated inhibition of mitochondrial quality control [PDF]
The 18-kDa TSPO (translocator protein) localizes on the outer mitochondrial membrane (OMM) and participates in cholesterol transport. Here, we report that TSPO inhibits mitochondrial autophagy downstream of the PINK1-PARK2 pathway, preventing essential ...

Differential Scales of Protein Quality Control [PDF]
Proteins are notorious for their unpleasant behavior-continually at risk of misfolding, collecting damage, aggregating, and causing toxicity and disease. To counter these challenges, cells have evolved elaborate chaperone and quality control networks that can resolve damage at the level of the protein, organelle, cell, or tissue. On the smallest scale,
