Members of this family, which are predominantly found in the protein 'Activator of Hsp90 ATPase' adopt a secondary structure consisting of an N-terminal alpha-helix leading into a four-stranded meandering antiparallel beta-sheet, followed by a C-terminal alpha-helix. The two helices are packed together, with the beta-sheet curving around them. They bind to the molecular chaperone HSP82 and stimulate its ATPase activity [1].	Domain
