Function

Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function (PubMed:16478993, PubMed:19696785). Engages with a range of client protein classes via its interaction with various co-chaperone proteins or complexes, that act as adapters, simultaneously able to interact with the specific client and the central chaperone itself. Recruitment of ATP and co-chaperone followed by client protein forms a functional chaperone. After the completion of the chaperoning process, properly folded client protein and co-chaperone leave HSP90 in an ADP-bound partially open conformation and finally, ADP is released from HSP90 which acquires an open conformation for the next cycle (PubMed:26991466, PubMed:27295069). Apart from its chaperone activity, it also plays a role in the regulation of the transcription machinery. HSP90 and its co-chaperones modulate transcription at least at three different levels. They first alter the steady-state levels of certain transcription factors in response to various physiological cues. Second, they modulate the activity of certain epigenetic modifiers, such as histone deacetylases or DNA methyl transferases, and thereby respond to the change in the environment. Third, they participate in the eviction of histones from the promoter region of certain genes and thereby turn on gene expression (PubMed:25973397). Antagonizes STUB1-mediated inhibition of TGF-beta signaling via inhibition of STUB1-mediated SMAD3 ubiquitination and degradation (PubMed:24613385). Promotes cell differentiation by chaperoning BIRC2 and thereby protecting from auto-ubiquitination and degradation by the proteasomal machinery (PubMed:18239673). Main chaperone involved in the phosphorylation/activation of the STAT1 by chaperoning both JAK2 and PRKCE under heat shock and in turn, activates its own transcription (PubMed:20353823). Involved in the translocation into ERGIC (endoplasmic reticulum-Golgi intermediate compartment) of leaderless cargos (lacking the secretion signal sequence) such as the interleukin 1/IL-1; the translocation process is mediated by the cargo receptor TMED10 (PubMed:32272059). (Microbial infection) Binding to N.meningitidis NadA stimulates monocytes (PubMed:21949862). Seems to interfere with N.meningitidis NadA-mediated invasion of human cells (Probable).

Activity summary

Hsp90 beta also known as Hsp90AB1 or Hsp90 protein is a heat shock protein of approximately 90 kDa. It is a molecular chaperone found in most eukaryotic cells. Hsp90 beta helps in the proper folding stabilization and degradation of many proteins. Unlike its isoform Hsp90 alpha Hsp90 beta has a more stable expression and is not typically induced by stress. This protein is primarily localized in the cytosol but can also be present in other cellular compartments depending on the cellular state.

Biological function summary

Hsp90 beta functions to maintain protein homeostasis and cellular integrity. It forms part of a multi-protein chaperone complex which includes cochaperones such as Hop Hsp70 and p23 necessary for its full functionality. Hsp90 beta supports the maturation of steroid hormone receptors kinases and other client proteins. It plays an important role in the cell cycle regulation through its interaction with various proteins ensuring proper cell division and growth.

Pathways

Hsp90 beta is deeply involved in signal transduction and cellular stress response pathways. Its interaction with the Akt pathway is significant for cell survival signals. Hsp90 beta also participates in the MAP kinase pathway affecting cell growth and differentiation. The protein associates with multiple kinases including RAF and Src which are important for downstream signaling.

Associated diseases and disorders

The dysregulation of Hsp90 beta is associated with cancer and neurodegenerative diseases. In cancer Hsp90 beta stabilizes many oncoproteins making it a potential therapeutic target for inhibiting tumor growth. It interacts with client proteins like the proto-oncogene c-Src promoting tumorigenesis. In neurodegenerative disorders such as Alzheimer's disease improper interaction between Hsp90 beta and tau proteins can contribute to disease progression impacting neuronal function.
