    BAG (Bcl-2-associated athanogene) proteins are molecular chaperone regulators that affect diverse cellular pathways. All members share a conserved motif, called the BAG domain (BD), which binds to Hsp70/Hsc70 family proteins and modulates their activity. We have determined the solution structure of BD from BAG4/SODD (silencer of death domains) by multidimensional nuclear magnetic resonance methods and compared it to the corresponding domain in BAG1 (Briknarov√°, K., Takayama, S., Brive, L., Havert, M. L., Knee, D. A., Velasco, J., Homma, S., Cabezas, E., Stuart, J., Hoyt, D. W., Satterthwait, A. C., Llin√°s, M., Reed, J. C., and Ely, K. R. (2001) Nat. Struct. Biol. 8, 349-352). The difference between BDs from these two BAG proteins is striking, and the structural comparison defines two subfamilies of mammalian BD-containing proteins. One subfamily includes the closely related BAG3, BAG4, and BAG5 proteins, and the other is represented by BAG1, which contains a structurally and evolutionarily distinct BD. BDs from both BAG1 and BAG4 are three-helix bundles; however, in BAG4, each helix in this bundle is three to four turns shorter than its counterpart in BAG1, which reduces the length of the domain by one-third. BAG4 BD thus represents a prototype of the minimal functional fragment that is capable of binding to Hsc70 and modulating its chaperone activity.
