Monomer (PubMed:24880080). Homodimer (PubMed:7588731, 18400751). Forms a complex with CDK6 and CDC37 (PubMed:9482106, 25486457). Interacts with UNC45A; binding to UNC45A involves 2 UNC45A monomers per HSP90AB1 dimer (PubMed:16478993). Interacts with CHORDC1 (By similarity). Interacts with DNAJC7 (PubMed:18620420). Interacts with FKBP4 (PubMed:15159550). May interact with NWD1 (PubMed:24681825). Interacts with SGTA (PubMed:16580629). Interacts with HSF1 in an ATP-dependent manner. Interacts with MET; the interaction suppresses MET kinase activity. Interacts with ERBB2 in an ATP-dependent manner; the interaction suppresses ERBB2 kinase activity. Interacts with HIF1A, KEAP1 and RHOBTB2 (PubMed:26517842). Interacts with STUB1 and SMAD3 (PubMed:24613385). Interacts with XPO1 and AHSA1 (PubMed:22022502, 25486457). Interacts with BIRC2 (PubMed:25486457). Interacts with KCNQ4; promotes cell surface expression of KCNQ4 (PubMed:23431407). Interacts with BIRC2; prevents auto-ubiquitination and degradation of its client protein BIRC2 (PubMed:18239673). Interacts with NOS3 (PubMed:23585225). Interacts with AHR; interaction is inhibited by HSP90AB1 phosphorylation on Ser-226 and Ser-255 (PubMed:15581363). Interacts with STIP1 and CDC37; upon SMYD2-dependent methylation (PubMed:24880080). Interacts with JAK2 and PRKCE; promotes functional activation in a heat shock-dependent manner (PubMed:20353823). Interacts with HSP90AA1; interaction is constitutive (PubMed:20353823). HSP90AB1-CDC37 chaperone complex interacts with inactive MAPK7 (via N-terminal half) in resting cells; the interaction is MAP2K5-independent and prevents from ubiquitination and proteasomal degradation (PubMed:23428871). Interacts with CDC25A; prevents heat shock-mediated CDC25A degradation and contributes to cell cycle progression (PubMed:22843495). Interacts with TP53 (via DNA binding domain); suppresses TP53 aggregation and prevents from irreversible thermal inactivation (PubMed:15358771). Interacts with TGFB1 processed form (LAP); inhibits latent TGFB1 activation (PubMed:20599762). Interacts with TRIM8; prevents nucleus translocation of phosphorylated STAT3 and HSP90AB1 (By similarity). Interacts with NR3C1 (via domain NR LBD) and NR1D1 (via domain NR LBD) (By similarity). Interacts with PDCL3 (By similarity). Interacts with TTC4 (via TPR repeats) (PubMed:18320024). Interacts with IL1B; the interaction facilitates cargo translocation into the ERGIC (PubMed:32272059). (Microbial infection) Protein on the cell surface interacts with N. meningitidis serogroup B adhesin A (nadA).
