摘要:
Onset of protein aggregation reflects failure of the cellular folding machinery to keep aggregation-prone protein from misfolding and accumulating into a non-degradable state. FRET based analysis and biochemical data reveal that cytosolic prion (cyPrP) and httQ-103 interact with the multifunctional protein glyceraldehyde-3-phosphate dehydrogenase (GAPDH) leading to few detectable aggregates in GAPDH-over expressing cells.The preventive effect of GAPDH suggests that this abundant and long-lived cytoplasmic protein has an active role in the shielding and maintenance, in soluble form of proteins as heterogeneous as huntingtin and cyPrP.
