Heat shock protein HSP 90-beta (HSP90AB1)

Molecular chaperone that promotes the maturation, structural maintenance and appropriate regulation of specific target proteins involved for example in cell cycle control and signal transduction. Undergoes a functional cycle that is connected 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 govern its substrate recognition, ATPase cycle and chaperone function (PubMed:16478993, PubMed:19696785).
