    8. Data support the multi-step nature of the Hsp90/Aha1-interaction, where the N-terminal domain of Aha1 interacts with both Hsp90 M domains upon induction of a partially closed conformation of the Hsp90 dimer. In addition, the data indicate that the C-terminal domain of Aha1 can adopt several conformations leading to a dynamic, polymorphic complex.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
