Molecular chaperone regulator BAG-1 (IPR017093)

Short name: BAG-1

Overlapping homologous superfamilies


Family relationships


This group represents a molecular chaperone regulator BAG-1 [PMID: 9873016]. BAG-1 contains a BAG domain that is formed by two antiparallel helices, while the third helix is extended away and stabilized by crystal-packing interactions [PMID: 15333932].

BAG-family proteins contain a single BAG domain, except for human BAG-5 which has four BAG repeats. The BAG domain is a conserved region located at the C terminus of the BAG-family proteins that binds the ATPase domain of Hsc70/Hsp70. BAG family proteins regulate chaperone protein activities through their interaction with Hsc70/Hsp70 [PMID: 12406544].
