The C-terminus of Hsp70 interacting protein (CHIP) is being considered to be a cellular quality control E3 ubiquitin ligase because of its ability to degrade misfolded proteins in association with heat shock chaperones. The neuroprotective role of CHIP also has been implicated in several familial neurodegenerative diseases including polyglutamine diseases. However, the regulation of the expression of CHIP under different stress conditions and its protective role thereon is unknown. Here we have shown that the mRNA level of CHIP is significantly increased in the cells exposed to oxidative, endoplasmic reticulum and proteasomal stress. CHIP also protected from various stress-induced cell death. Finally, we have demonstrated upregulation of CHIP mRNA levels in the expanded polyglutamine protein expressing cells. Our result suggests that the upregulation of CHIP under various stress environments is an adaptive response of the cells to deal with the excess burden of misfolded protein.
