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.
Specificity
Natural and recombinant Mouse Heat shock protein HSP 90-alpha
Homodimer. Interacts with AHSA1, FNIP1, HSF1, SMYD3 and TOM34 (By similarity). Interacts with TERT; the interaction, together with PTGES3, is required for correct assembly and stabilization of the TERT holoenzyme complex (By similarity). Interacts with CHORDC1 and DNAJC7.
