Refined structure of the C-terminal domain of DNAJB6b

Structural highlights

7jsq is a 1 chain structure with sequence from Homo sapiens. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	Solution NMR
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Disease

DNJB6_HUMAN Autosomal dominant limb-girdle muscular dystrophy type 1D. The disease is caused by mutations affecting the gene represented in this entry. There is evidence that LGMDD1 is caused by dysfunction of isoform B (PubMed:22366786).^[1]

Function

DNJB6_HUMAN Plays an indispensable role in the organization of KRT8/KRT18 filaments. Acts as an endogenous molecular chaperone for neuronal proteins including huntingtin. Suppresses aggregation and toxicity of polyglutamine-containing, aggregation-prone proteins. Isoform B but not isoform A inhibits huntingtin aggregation. Has a stimulatory effect on the ATPase activity of HSP70 in a dose-dependent and time-dependent manner and hence acts as a co-chaperone of HSP70. Also reduces cellular toxicity and caspase-3 activity.^[2] ^[3] ^[4] ^[5] ^[6]
