| Open AccessTertiary structure and conformational dynamics of the anti-amyloidogenic chaperone DNAJB6b at atomistic resolution
Adupa et al show how the anti-amyloidogenic molecular chaperone DNAJB6 adopts three conformational states that determine the accessibility of its substrate binding domain. In all states, interactions with HSP70 are shielded, suggesting that functional interactions only may occur upon substrate binding.
