DnaJ homolog subfamily B member 6 is a protein that in humans is encoded by the DNAJB6 gene.[3][4][5]
Function
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.[5]
Interactions
DNAJB6 has been shown to interact with Keratin 18.[6] It has been also shown that the aggregation of Aβ42 (a process involved in e.g. Alzheimer's disease) is retarded by DNAJB6 in a concentration-dependent manner, extending to very low sub-stoichiometric molar ratios of chaperone to peptide.[7]
