Involved in several processes, including cellular response to brain-derived neurotrophic factor stimulus; nervous system development; and regulation of signal transduction. Located in several cellular components, including axon; endosome; and postsynaptic density. Is expressed in 4th ventricle lateral recess; cerebral cortex marginal layer; and lateral ventricle choroid plexus. Orthologous to human TMEM108 (transmembrane protein 108).
