In Western blot, ab303516 was shown to bind specifically to Hsp90 alpha. A band was observed at 90 kDa in wild-type 293T cell lysates with no signal observed at this size in Hsp90 alpha knockout cell line. To generate this image, wild-type and Hsp90 alpha knockout 293T cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Hsp90 alpha also known as Hsp90AA1 or 5G5 is a molecular chaperone with an approximate molecular weight of 90 kDa. It plays an important role in the folding stability and function of many client proteins. This protein is expressed ubiquitously in eukaryotic cells with high levels in the cytoplasm and the endoplasmic reticulum. Hsp90 alpha operates through a unique ATPase-driven chaperone cycle that modulates protein conformations helping in the assembly and disassembly of protein complexes.
Biological function summary

Hsp90 alpha assists in maintaining protein homeostasis and is part of a larger chaperome complex including co-chaperones and other chaperones such as Hsp70. It plays an important role in stress response by stabilizing proteins and preventing aggregation. Hsp90 alpha is essential for the normal function of several kinases and transcription factors which are important for cell signaling and regulation processes. It functions as a mediator for cellular response to environmental cues.

Pathways

Hsp90 alpha is an integral component in the signal transduction and cell cycle control pathways. It interacts with various signaling proteins and receptors like AKT and steroid hormone receptors to facilitate their proper folding and activation. Furthermore Hsp90 alpha influences the MAPK/ERK pathway playing a role in cell proliferation and differentiation. Its interaction with Hsp90 protein clients creates a regulatory framework across multiple pathways allowing precise control over cellular function.

Hsp90 alpha is linked to cancer and neurodegenerative diseases. Its enhanced expression in tumors correlates with the stabilization of oncogenic client proteins such as HER2 contributing to cancer progression. Additionally Hsp90 alpha relates to disorders like Alzheimer's disease due to its role in handling misfolded proteins. The protein interacts with co-chaperones like H1L1 which may influence its impact on disease outcomes highlighting the therapeutic potential of targeting Hsp90 alpha in these conditions.

Target data

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 that is linked to its ATPase activity which is essential for its chaperone 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 : 11274138, PubMed : 12526792, PubMed : 15577939, PubMed : 15937123, PubMed : 27353360, PubMed : 29127155). 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 (PubMed : 29127155). 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). Plays a critical role in mitochondrial import, delivers preproteins to the mitochondrial import receptor TOMM70 (PubMed : 12526792). 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 (PubMed : 25973397). In the first place, they alter the steady-state levels of certain transcription factors in response to various physiological cues (PubMed : 25973397). 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 (PubMed : 25973397). Third, they participate in the eviction of histones from the promoter region of certain genes and thereby turn on gene expression (PubMed : 25973397). Binds bacterial lipopolysaccharide (LPS) and mediates LPS-induced inflammatory response, including TNF secretion by monocytes (PubMed : 11276205). Antagonizes STUB1-mediated inhibition of TGF-beta signaling via inhibition of STUB1-mediated SMAD3 ubiquitination and degradation (PubMed : 24613385). Mediates the association of TOMM70 with IRF3 or TBK1 in mitochondrial outer membrane which promotes host antiviral response (PubMed : 20628368, PubMed : 25609812)..
