Protein turnover chaperones
Did you know?
WebbChaperones are proteins that guide proteins along the proper pathways for folding. They protect proteins when they are in the process of folding, shielding them from other proteins that might bind and hinder the process. Webb9 sep. 2006 · Chaperones are induced by proteotoxic environmental stress at the level of transcription, when the cytosolic level of damaged, misfolded proteins is sufficient to displace heat shock factor (HSF) from its inhibitory chaperone complex. Thus, chaperones are also known as stress or heat shock proteins (Morimoto 1998 ).

Of the nine human herpesviruses, the VZV genome is the smallest (~124 kbp), lacking any known inhibitors of autophagy, such as the herpes simplex virus ICP34.5 neurovirulence gene. Therefore, this review assesses the evidence for VZV-induced cellular stress, endoplasmic-reticulum … Webb16 dec. 2024 · Finally, our third hypothesis was that elevated chaperone levels would increase general protein dosage, by affecting expression capacity or protein turnover.
