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 linked to its ATPase activity. This cycle probably
CC induces conformational changes in the client proteins, thereby causing
CC their 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. Apart from its chaperone
CC activity, it also plays a role in the regulation of the transcription
CC machinery. HSP90 and its co-chaperones modulate transcription at least
CC at three different levels. They first 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. Antagonizes STUB1-
CC mediated inhibition of TGF-beta signaling via inhibition of STUB1-
CC mediated SMAD3 ubiquitination and degradation. Promotes cell
CC differentiation by chaperoning BIRC2 and thereby protecting from auto-
CC ubiquitination and degradation by the proteasomal machinery. Main
CC chaperone involved in the phosphorylation/activation of the STAT1 by
CC chaperoning both JAK2 and PRKCE under heat shock and in turn, activates
CC its own transcription. Involved in the translocation into ERGIC
CC (endoplasmic reticulum-Golgi intermediate compartment) of leaderless
CC cargos (lacking the secretion signal sequence) such as the interleukin
CC 1/IL-1; the translocation process is mediated by the cargo receptor
CC TMED10. {ECO:0000250|UniProtKB:P08238}.
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. {ECO:0000250|UniProtKB:P08238}.
CC -!- SUBUNIT: Monomer. Homodimer (By similarity). Forms a complex with CDK6
CC and CDC37. Interacts with UNC45A; binding to UNC45A involves 2 UNC45A

CC similarity). Interacts with DNAJC7. Interacts with FKBP4. May interact
CC with NWD1. Interacts with SGTA. Interacts with HSF1 in an ATP-dependent
CC manner. Interacts with MET; the interaction suppresses MET kinase
CC activity. Interacts with ERBB2 in an ATP-dependent manner; the
CC interaction suppresses ERBB2 kinase activity. Interacts with HIF1A,
CC KEAP1 and RHOBTB2. Interacts with STUB1 and SMAD3. Interacts with XPO1
CC and AHSA1. Interacts with BIRC2. Interacts with KCNQ4; promotes cell

CC phosphorylation on Ser-226 and Ser-257. Interacts with STIP1 and CDC37;
CC upon SMYD2-dependent methylation. Interacts with JAK2 and PRKCE;
CC promotes functional activation in a heat shock-dependent manner.
CC Interacts with HSP90AA1; interaction is constitutive. HSP90AB1-CDC37
CC chaperone complex interacts with inactive MAPK7 (via N-terminal half)
CC in resting cells; the interaction is MAP2K5-independent and prevents
CC from ubiquitination and proteasomal degradation. Interacts with CDC25A;
CC prevents heat shock-mediated CDC25A degradation and contributes to cell
CC cycle progression. Interacts with TP53 (via DNA binding domain);
CC suppresses TP53 aggregation and prevents from irreversible thermal
CC inactivation. Interacts with TGFB1 processed form (LAP); inhibits
CC latent TGFB1 activation (By similarity). Interacts with TRIM8; prevents
