| Post Translational Modifications | Ser-10 phosphorylation induces an order-to-disorder transition triggering the interaction with Lys-58. This conformational switch modulates DNAJC5's cellular functions by reducing binding to syntaxin and synaptogamin without altering HSC70 interactions. Palmitoylated. Could be palmitoylated by DHHC3, DHHC7, DHHC15 and DHHC17. Palmitoylation occurs probably in the cysteine-rich domain and regulates DNAJC5 membrane attachment. |
| Function | Acts as a general chaperone in regulated exocytosis. Acts as a co-chaperone for the SNARE protein SNAP-25. Involved in the calcium-mediated control of a late stage of exocytosis. May have an important role in presynaptic function. May be involved in calcium-dependent neurotransmitter release at nerve endings. |
