WebMay 18, 2024 · Huntington's disease (HD) is caused by CAG repeat expansion in the huntingtin gene. The expanded polyglutamine (polyQ) repeat of the encoded protein leads to protein misfolding and aggregation, resulting in increased neuronal cell death. DNAJ co-chaperones play a crucial role in transferring misfold … WebOct 26, 2024 · Huntington's disease (HD) is an inherited neurodegenerative disorder, caused by an abnormal polyglutamine (polyQ) expansion in the huntingtin protein (Htt). Mitochondrial dysfunction and impairment of the ubiquitin-proteasome system (UPS) are hallmarks of HD neurons. The extraneural manifestations of HD are still unclear.
WebDec 12, 2013 · Protein misfolding and other errors in protein generation occur frequently within cells, and the cell has evolved a range of mechanisms to ensure proper folding and to eliminate aggregated or otherwise damaged proteins.
