General annotation (Comments)

Function

Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function By similarity.

Subunit structure

Homodimer. Interacts with AHSA1, FNIP1, HSF1, SMYD3 and TOM34. Interacts with TERT; the interaction, together with PTGES3, is required for correct assembly and stabilization of the TERT holoenzyme complex. Interacts with CHORDC1 and DNAJC7. Interacts with STUB1 and UBE2N; may couple the chaperone and ubiquitination systems By similarity.

Subcellular location

Cytoplasm By similarity. Melanosome By similarity.

Domain

The TPR repeat-binding motif mediates interaction with TPR repeat-containing proteins like the co-chaperone STUB1 By similarity.

Post-translational modification

S-nitrosylated; negatively regulates the ATPase activity and the activation of eNOS by HSP90AA1 By similarity.

ISGylated By similarity.

Sequence similarities

Belongs to the heat shock protein 90 family.
