The balanced regulation of Hsc70 by DNJ-13 and UNC-23 is required for muscle functionality.

Abstract excerpt

The molecular chaperone Hsc70 assists in the folding of non-native proteins together with its J domain- and BAG domain-containing cofactors. In Caenorhabditis elegans, two BAG domain-containing proteins can be identified, one of them being UNC-23, whose mutation induces severe motility dysfunctions. Using reporter strains, we find that the full-length UNC-23, in contrast to C-terminal fragments, localizes...
