Predicted to enable lysophosphatidic acid binding activity; protein homodimerization activity; and sulfatide binding activity. Predicted to be involved in several processes, including cholesterol metabolic process; ganglioside metabolic process; and lysosomal lumen acidification. Predicted to act upstream of or within cellular macromolecule catabolic process; locomotion involved in locomotory behavior; and visual perception. Predicted to be located in several cellular components, including early endosome; endoplasmic reticulum lumen; and membrane raft. Predicted to be active in endoplasmic reticulum and membrane. Human ortholog(s) of this gene implicated in neuronal ceroid lipofuscinosis; neuronal ceroid lipofuscinosis 4A; and neuronal ceroid lipofuscinosis 6. Orthologous to human CLN6 (CLN6 transmembrane ER protein). [provided by Alliance of Genome Resources, Apr 2022]
