CC -!- FUNCTION: Molecular chaperone that promotes the maturation, structural
CC maintenance and proper regulation of specific target proteins involved
CC for instance in cell cycle control and signal transduction. Undergoes a
CC functional cycle that is linked to its ATPase activity which is
CC essential for its chaperone activity. This cycle probably induces
CC conformational changes in the client proteins, thereby causing their
CC activation. Interacts dynamically with various co-chaperones that
CC modulate its substrate recognition, ATPase cycle and chaperone
CC function. Engages with a range of client protein classes via its
CC interaction with various co-chaperone proteins or complexes, that act
CC as adapters, simultaneously able to interact with the specific client
CC and the central chaperone itself. Recruitment of ATP and co-chaperone
CC followed by client protein forms a functional chaperone. After the
CC completion of the chaperoning process, properly folded client protein
CC and co-chaperone leave HSP90 in an ADP-bound partially open
CC conformation and finally, ADP is released from HSP90 which acquires an
CC open conformation for the next cycle. Plays a critical role in
CC mitochondrial import, delivers preproteins to the mitochondrial import
CC receptor TOMM70. Apart from its chaperone activity, it also plays a
CC role in the regulation of the transcription machinery. HSP90 and its
CC co-chaperones modulate transcription at least at three different
CC levels. In the first place, they alter the steady-state levels of
CC certain transcription factors in response to various physiological
CC cues. Second, they modulate the activity of certain epigenetic
CC modifiers, such as histone deacetylases or DNA methyl transferases, and
CC thereby respond to the change in the environment. Third, they
CC participate in the eviction of histones from the promoter region of
CC certain genes and thereby turn on gene expression. Binds bacterial
CC lipopolysaccharide (LPS) and mediates LPS-induced inflammatory
CC response, including TNF secretion by monocytes. Antagonizes STUB1-
CC mediated inhibition of TGF-beta signaling via inhibition of STUB1-
CC mediated SMAD3 ubiquitination and degradation. Mediates the association
CC of TOMM70 with IRF3 or TBK1 in mitochondrial outer membrane which
CC promotes host antiviral response. {ECO:0000250|UniProtKB:P07900}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.10;
CC Evidence={ECO:0000250|UniProtKB:P07900};
CC -!- ACTIVITY REGULATION: In the resting state, through the dimerization of
CC its C-terminal domain, HSP90 forms a homodimer which is defined as the
CC open conformation. Upon ATP-binding, the N-terminal domain undergoes
CC significant conformational changes and comes in contact to form an
CC active closed conformation. After HSP90 finishes its chaperoning tasks
CC of assisting the proper folding, stabilization and activation of client
CC proteins under the active state, ATP molecule is hydrolyzed to ADP
CC which then dissociates from HSP90 and directs the protein back to the
CC resting state. Co-chaperone TSC1 promotes ATP binding and inhibits
CC HSP90AA1 ATPase activity. Binding to phosphorylated AHSA1 promotes
CC HSP90AA1 ATPase activity. Inhibited by geldanamycin, Ganetespib (STA-
CC 9090) and SNX-2112. {ECO:0000250|UniProtKB:P07900}.
CC -!- SUBUNIT: Homodimer. Identified in NR3C1/GCR steroid receptor-chaperone
CC complexes formed at least by NR3C1, HSP90AA1 and a variety of proteins
CC containing TPR repeats such as FKBP4, FKBP5, PPID, PPP5C or STIP1.
CC Forms a complex containing HSP90AA1, TSC1 and TSC2; TSC1 is required to
CC recruit TCS2 to the complex. The closed form interacts (via the middle
CC domain and TPR repeat-binding motif) with co-chaperone TSC1 (via C-
CC terminus). Interacts with TOM34. Interacts with TERT; the interaction,
CC together with PTGES3, is required for correct assembly and
CC stabilization of the TERT holoenzyme complex. Interacts with CHORDC1
CC and DNAJC7. Interacts with STUB1 and UBE2N; may couple the chaperone
CC and ubiquitination systems. Interacts (via TPR repeat-binding motif)
CC with PPP5C (via TPR repeats); the interaction is direct and activates
CC PPP5C phosphatase activity. Following LPS binding, may form a complex
CC with CXCR4, GDF5 and HSPA8. Interacts with KSR1. Interacts with co-
CC chaperone CDC37 (via C-terminus); the interaction inhibits HSP90AA1
CC ATPase activity. May interact with NWD1. Interacts with FNIP1 and
CC FNIP2; the interaction inhibits HSP90AA1 ATPase activity. Interacts
CC with co-chaperone AHSA1 (phosphorylated on 'Tyr-223'); the interaction
CC activates HSP90AA1 ATPase activity and results in the dissociation of
CC TSC1 from HSP90AA1. Interacts with FLCN in the presence of FNIP1.
CC Interacts with HSP70, STIP1 and PTGES3. Interacts with SMYD3; this
CC interaction enhances SMYD3 histone-lysine N-methyltransferase.
CC Interacts with SGTA (via TPR repeats). Interacts with TTC1 (via TPR
CC repeats). Interacts with HSF1 in an ATP-dependent manner. Interacts
CC with MET; the interaction suppresses MET kinase activity. Interacts
CC with ERBB2 in an ATP-dependent manner; the interaction suppresses ERBB2
CC kinase activity. Interacts with HIF1A, KEAP1 and RHOBTB2. Interacts
CC with HSF1; this interaction is decreased in a IER5-dependent manner,
CC promoting HSF1 accumulation in the nucleus, homotrimerization and DNA-
CC binding activities. Interacts with STUB1 and SMAD3. Interacts with
CC HSP90AB1; interaction is constitutive (By similarity). Interacts with
CC HECTD1 (via N-terminus) (By similarity). Interacts with NR3C1 (via
CC domain NR LBD) and NR1D1 (via domain NR LBD) (By similarity). Interacts
CC with NLPR12 (By similarity). Interacts with PDCL3 (By similarity).
CC Interacts with TOMM70; the interaction is required for preprotein
CC mitochondrial import. Interacts with TOMM70, IRF3 and TBK1; the
CC interactions are direct and mediate the association of TOMM70 with IRF3
CC and TBK1 (By similarity). Forms a complex with ASL, ASS1 and NOS2; the
CC complex regulates cell-autonomous L-arginine synthesis and citrulline
CC recycling while channeling extracellular L-arginine to nitric oxide
CC synthesis pathway. {ECO:0000250|UniProtKB:P07900,
