CC   -!- FUNCTION: Molecular chaperone that promotes the maturation, structural
CC       maintenance and proper regulation of specific target proteins involved
CC       for instance in cell cycle control and signal transduction. Undergoes a
CC       functional cycle that is linked to its ATPase activity. This cycle
CC       probably induces conformational changes in the client proteins, thereby
CC       causing their activation. Interacts dynamically with various co-
CC       chaperones that modulate its substrate recognition, ATPase cycle and
CC       chaperone function. Required for piRNA biogenesis by facilitating
CC       loading of piRNAs into PIWI proteins (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. Interacts with shu (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the heat shock protein 90 family. {ECO:0000305}.
