Protein quality control and mitochondria

Protein aggregates are toxic for mitochondrial function, and thus disrupt the supply of chemical energy to their host cells. An LMU team has characterized a protein complex that prevents the build-up of such deposits in the ...

Protein complex may help prevent neurodegenerative diseases

Researchers from the Universities of Konstanz (Germany), Leeds (U.K.) and Stanford (U.S.) have discovered that the nascent polypeptide-associated complex (NAC) prevents the aggregation of proteins associated with several ...

Scientists develop novel method to monitor molecular aggregation

Chiral molecules are defined as molecules that are non-superimposable on their mirror images, much like that of left and right human hand bone structure. There are many examples of chiral molecules in nature, including proteins ...

Misfolded proteins serve as 'inherited memory' of toxic insults

Protein aggregates have a bad reputation in conditions such as Alzheimer's disease and Parkinson's disease, but in bacteria, inheritance of aggregates by daughter cells may help protect against the same toxic stresses that ...
