General Information

General Information Comment Organism
metabolism Hsc70 plays a crucial role in degradation of mutant CFTR by the ubiquitin-proteasome system. The small molecule apoptozole has high cellular potency to promote membrane trafficking of mutant DeltaF508 and its chloride channel activity in cystic fibrosis cells. Apoptozole inhibits the ATPase activity of Hsc70 by binding to its ATPase domain and apoptozole suppresses ubiquitination of DeltaF508 maybe by blocking interaction of the mutant with Hsc70 and E3 ubiquitin ligase CHIP, and, as a consequence, it enhances membrane trafficking of the mutant Homo sapiens
