Predicted to enable calcium-dependent protein binding activity and sulfatide binding activity. Predicted to be involved in several processes, including modulation of chemical synaptic transmission; regulation of vesicle-mediated transport; and vacuole organization. Predicted to act upstream of or within several processes, including autophagosome maturation; regulation of cellular protein metabolic process; and regulation of filopodium assembly. Located in plasma membrane. Colocalizes with Golgi apparatus and endosome. Human ortholog(s) of this gene implicated in neuronal ceroid lipofuscinosis 3. Orthologous to human CLN3 (CLN3 lysosomal/endosomal transmembrane protein, battenin). [provided by Alliance of Genome Resources, Apr 2022]
