Predicted to enable ATP-dependent protein binding activity. Involved in chaperone-mediated protein folding and regulation of synaptic vesicle cycle. Acts upstream of or within negative regulation of neuron apoptotic process. Located in neuromuscular junction and synaptic vesicle. Is active in presynapse. Human ortholog(s) of this gene implicated in neuronal ceroid lipofuscinosis 4B. Orthologous to human DNAJC5 (DnaJ heat shock protein family (Hsp40) member C5).
