Target Background

Function
Interacts with DnaK and GrpE to disassemble a protein complex at the origins of replication of phage lambda and several plasmids. Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, DnaK and GrpE are required for fully efficient folding.
Gene References into Functions
  1. BAH1 could partially compensate for the DnaJ' zinc finger domain in vivo, and that it was dependent on the zinc finger domain of BAH1. PMID: 29260303
  2. DnaJ mutant is impaired in biofilm development when exposed to 42 degrees C for 2 h. PMID: 26638536
  3. DnaJ, without the aid of DnaK/GrpE, is capable of increasing the efficiency of KplE1 excision by causing a conformational stabilization that allows TorI to adopt a more favorable conformation for binding to its specific DNA target PMID: 22378785
  4. DnaJ dramatically enhances both TorI binding to its DNA target and excisive recombination in vitro. PMID: 21908845
  5. DnaJ distinguishes the substrate conformation and is able to adapt the use of the G/F-rich region to form stable substrate complexes PMID: 20729526
  6. in the chaperone-dependent disaggregation process, DnaK and DnaJ bind to aggregates prior to ClpB action PMID: 15302880
  7. In a DnaJ mutant both CbpA and DjlA are required for efficient DnaK mediated protein dissaggregation at 42 degrees C. PMID: 15489435
  8. Two cysteine residues only in the -CXXC- motif are critical to form an active site and indispensable to the thiol-disulfide oxidoreductase activity of DnaJ. Each -CXXC- motif in zinc-finger domain Zn2, but not in Zn1, functions as an active site. PMID: 15683252
  9. the C-terminal (331-376) residues are directly involved in dimerization, and the dimeric structure of DnaJ is necessary for its chaperone activity but not required for the thiol-disulfide oxidoreductase activity PMID: 15849180
