Summaries for DNAJB6 Gene

Entrez Gene Summary for DNAJB6 Gene

  • This gene encodes a member of the DNAJ protein family. DNAJ family members are characterized by a highly conserved amino acid stretch called the 'J-domain' and function as one of the two major classes of molecular chaperones involved in a wide range of cellular events, such as protein folding and oligomeric protein complex assembly. This family member may also play a role in polyglutamine aggregation in specific neurons. Alternative splicing of this gene results in multiple transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

GeneCards Summary for DNAJB6 Gene

DNAJB6 (DnaJ (Hsp40) Homolog, Subfamily B, Member 6) is a Protein Coding gene. Diseases associated with DNAJB6 include muscular dystrophy, limb-girdle, type 1e and dnajb6-related myofibrillar myopathy. Among its related pathways are Mechanisms of CFTR activation by S-nitrosoglutathione (normal and CF) and Mechanisms of CFTR activation by S-nitrosoglutathione (normal and CF). GO annotations related to this gene include chaperone binding and ATPase activator activity. An important paralog of this gene is DNAJB7.

UniProtKB/Swiss-Prot for DNAJB6 Gene

  • 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.
