FNIP1 and FNIP2 facilitate FLCN binding to Hsp90 chaperone. Our results suggest that FNIP1 is a potent inhibitor of Hsp90 ATPase activity, as 200 nM of FNIP1 inhibits Hsp90 ATPase activity by 50-fold. FNIP2 also has shown inhibitory activity towards Hsp90; however, it required 1.6 μM of FNIP2 to inhibit the ATPase activity by eightfold. Although we use the term ‘inhibition' here, FNIPs seem only to be slowing the chaperone cycle. |

The type I lissencephaly gene product LIS1, a key regulator of cytoplasmic dynein, is critical for cell proliferation, survival, and neuronal migration. However, little is known about the regulation of LIS1. Here, we identify a previously uncharacterized mammalian homolog of Aspergillus NudC, NudCL2 (NudC-like protein 2), as a regulator of LIS1. NudCL2 is localized to the centrosome in interphase, and spindle poles and kinetochores during mitosis, a pattern similar to the localization of LIS1 and cytoplasmic dynein. Depletion of NudCL2 destabilized LIS1 and led to phenotypes resembling those of either dynein or LIS1 deficiency. NudCL2 complexed with and enhanced the interaction between LIS1 and Hsp90. Either disruption of the LIS1-Hsp90 interaction with the C terminus of NudCL2 or inhibition of Hsp90 chaperone function by geldanamycin decreased LIS1 stability. |

We demonstrate that TRAF6 ubiquitinates the proform of AEP through K63-linked polyubiquitin, reversible by USP17, and forms a complex with HSP90α to subsequently promote pro-AEP intracellular stability as well as secretion. We now present evidence that AEP is a substrate for TRAF6 ubiquitination, resulting in AEP/TRAF6/HSP90α complex formation. |

Hsp90 chaperone cycle is tightly regulated by another group of proteins referred to as ‘co-chaperones'. Their stability does not depend on Hsp90 function but they interact with distinct Hsp90 conformational states, providing directionality to the Hsp90 cycle. Furthermore, certain co-chaperones, such as HOP and Cdc37p50 inhibit the Hsp90 chaperone cycle, assisting in delivery of distinct sets of client proteins (steroid hormone receptors and kinases, respectively) to the Hsp90 chaperone machine. |

The unliganded AR resides predominately in the cytoplasm as a heteromeric complex with hsp90 and other chaperone proteins. These chaperone proteins maintain AR in a form that is receptive to ligand binding. Regulation of gene expression by androgen-activated AR occurs through receptor nuclear translocation, dimerization, and binding to androgen response elements (AREs) in the DNA of target genes. |

By immunoprecipitation, we present evidence that Hakai interacts with Hsp90 chaperone complex in several epithelial cells and demonstrate that is a novel Hsp90 client protein. Interestingly, by overexpressing and knocking-down experiments with Hakai, we identified Annexin A2 as a Hakai-regulated protein. Interestingly, geldanamycin-induced Hakai degradation is accompanied by an increased expression of E-cadherin and Annexin A2. Hsp90 participates in the correct folding of its client proteins, allowing them to maintain their stability and activity. |

The Tom70 receptor is a membrane-localized cochaperone that integrates the Hsp70/Hsp90 chaperones with mitochondrial preprotein targeting and translocation. In mammals, preprotein in the cytosol is associated with both Hsp90 and Hsp70 in a multichaperone complex, and docking of Hsp90 and/or Hsp70 onto Tom70 is essential for preprotein targeting. |

We demonstrate that Hectd1 is a functional ubiquitin ligase and that one of its substrates is Hsp90, a chaperone protein with both intra- and extracellular clients. Identification of Hsp90 in both proteomic screens suggested that members of the Hsp90 superfamily may be substrates of Hectd1. Myc-Hectd1ANK and HA-Hsp90bd (the fragment identified in the yeast two-hybrid screen) bind in an in vitro binding assay (Fig. 3 D) and when coexpressed in HEK293T cells. Hectd1 is required for K63-linked Ubn of Hsp90. Together, these results demonstrate that Hectd1-dependent Ubn of Hsp90 targets it away from the membrane and the secretory pathway. |
