Interactioni

Subunit structurei

Part of the Cpn60 complex composed of 7 alpha and 7 beta subunits. Can also form a complex composed of 14 beta subunits only. Both complexes show ATPase activity. The Cpn60 complex interacts with the Cpn10 complex. Interacts with RAB during heat stress.3 Publications
