    text
  • membrane-bound
  • has a weak membrane affinity that allows the protein to locate its partner Golgi-localized DHHC proteins directly by membrane "sampling" (Greaves 2008)
  • basic FUNCTION
  • playing a role in exocytosis of large dense core vesicles
  • having an important role in presynaptic function
  • involved in calcium-dependent neurotransmitter release at nerve endings
  • extensively palmitoylated DnaJ-family chaperone, which exerts an important neuroprotective function (Greaves 2008)
  • involved in MARCKS targeting to and/or preferentially attaching to mucin granule membranes (Park 2008)
  • with HSP70, and their interactions with MARCKS, are involved in mucin secretion (Park 2008)
  • SNARE-binding protein involved in the vesicular trafficking of neurotransmitters and other exocytic processes

    a component
  • DNAJC5 appeared to form a trimeric complex with MARCKS and HSP70 associated with mucin granule membranes within airway epithelial cells (Park 2008)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • Hsp70 binds directly to DNAJC5, but MARCKS binding to DNAJC5 appears to require the presence of Hsp70 (Lin 2010)
  • is involved in insulin resistance by interrupting SLC2A4 vesicle docking with the plasma membrane
  • DNAJC5 facilitates USP19-dependent unconventional secretion of misfolded cytosolic proteins
  • cell & other
    REGULATION
    Other regulated by palmitoylation (is required for the intracellular sorting and function of DNAJC5, and thus it is important to understand how this essential modification of DNAJC5 is regulated) (Greaves 2008)
