One BAG Does Not Fit All: Differences and Similarities of BAG Family Members in Mediating Central Nervous System Homeostasis.

ABSTRACT: There is an increasing awareness that B-cell lymphoma 2 (Bcl-2)-associated athanogene (BAG) proteins play critical roles in maintaining neural homeostasis and that their dysregulation contributes to neurological disorders. This protein family, which comprises 9 members, is evolutionarily conserved, with each member having at least one BAG domain that binds to the nucleotide-binding domains of Hsp70 family members. Collectively, these proteins are essential for the proper functioning of the central nervous system (CNS). Although numerous studies have focused on a specific BAG protein, an understanding of how BAG family members may act cooperatively to maintain cellular homeostasis is needed. In this review, we give an overview of the BAG domain interactors Hsp72, Hsp70.2, CHIP, and METTL3,
