When the proteasome machinery is deregulated, misfolded proteins are eliminated by forming aggresomes. To this end, poly-ubiquitinated misfolded proteins bind to a complex comprising of Transitional endoplasmic reticulum ATPase (VCP), Histone deacetylase 6 (HDAC6), Heat shock protein HSP 90 (HSP90) and Heat shock factor protein 1 (HSF1). HDAC6 in the complex interacts with the ubiquitin molecules in the misfolded proteins. Following this binding event, this complex starts dissociating (Boyault C et al. 2007).
