PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • three BAG domains of BAG1, BAG2, and BAG3 interact specifically with the HSPA8 ATPase domain
  • C terminal BAG domain binding HSPA8/HSP70 ATPase domain

    CATEGORY chaperone/stress
    SUBCELLULAR LOCALIZATION
    basic FUNCTION
  • negative regulator of Hsp70 chaperone activity
  • inhibits the chaperone activity of HSP70/HSC70 by promoting substrate release
  • compete with RPL29 for binding to the HSPA8/HSP70 ATPase domain and promote substrate release
  • inhibits the ubiquitin ligase activity of STUB1 by abrogating the STUB1/E2 cooperation and stimulates the chaperone-assisted maturation of CFTR

    DNA
    RNA
    small molecule
    protein
  • binds to the ATPase domain of HSP70/HSC chaperones
  • associates with STUB1 as part of a ternary complex with HSPA8, and BAG2 (provides a cochaperone-dependent regulatory mechanism for preventing unregulated ubiquitylation of misfolded proteins by STUB1)
  • BAG2 contributes to HSP70 stabilization in tissues other than testes
