CC   -!- FUNCTION: Molecular chaperone that promotes the maturation,
CC       structural maintenance and proper regulation of specific target
CC       proteins involved for instance in cell cycle control and signal
CC       transduction. Undergoes a functional cycle that is linked to its
CC       ATPase activity. This cycle probably induces conformational
CC       changes in the client proteins, thereby causing their activation.
CC       Interacts dynamically with various co-chaperones that modulate its
CC       substrate recognition, ATPase cycle and chaperone function.
CC       Engages with a range of client protein classes via its interaction
CC       with various co-chaperone proteins or complexes, that act as
CC       adapters, simultaneously able to interact with the specific client
CC       and the central chaperone itself. Recruitment of ATP and co-
CC       chaperone followed by client protein forms a functional chaperone.
CC       After the completion of the chaperoning process, properly folded
CC       client protein and co-chaperone leave HSP90 in an ADP-bound
CC       partially open conformation and finally, ADP is released from
CC       HSP90 which acquires an open conformation for the next cycle.
CC       Apart from its chaperone activity, it also plays a role in the
CC       regulation of the transcription machinery. HSP90 and its co-
CC       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
CC       transferases, and thereby respond to the change in the
CC       environment. Third, they participate in the eviction of histones
CC       from the promoter region of certain genes and thereby turn on gene
CC       expression. Antagonizes STUB1-mediated inhibition of TGF-beta
CC       signaling via inhibition of STUB1-mediated SMAD3 ubiquitination
CC       and degradation. Promotes cell differentiation by chaperoning
CC       BIRC2 and thereby protecting from auto-ubiquitination and
CC       degradation by the proteasomal machinery. Main chaperone that is
CC       involved in the phosphorylation/activation of the STAT1 by
CC       chaperoning both JAK2 and PRKCE under heat shock and in turn,
CC       activates its own transcription. {ECO:0000250|UniProtKB:P08238}.
CC   -!- ACTIVITY REGULATION: In the resting state, through the
CC       dimerization of its C-terminal domain, HSP90 forms a homodimer
CC       which is defined as the open conformation. Upon ATP-binding, the
CC       N-terminal domain undergoes significant conformational changes and
CC       comes in contact to form an active closed conformation. After
CC       HSP90 finishes its chaperoning tasks of assisting the proper
CC       folding, stabilization and activation of client proteins under the
CC       active state, ATP molecule is hydrolyzed to ADP which then
CC       dissociates from HSP90 and directs the protein back to the resting
CC       state. {ECO:0000250|UniProtKB:P08238}.
CC   -!- SUBUNIT: Monomer. Homodimer (By similarity). Forms a complex with
CC       CDK6 and CDC37. Interacts with UNC45A; binding to UNC45A involves

CC       interaction suppresses MET kinase activity. Interacts with ERBB2
CC       in an ATP-dependent manner; the interaction suppresses ERBB2
CC       kinase activity. Interacts with HIF1A, KEAP1 and RHOBTB2.

CC       and proteasomal degradation. Interacts with CDC25A; prevents heat
CC       shock-mediated CDC25A degradation and contributes to cell cycle
