Predicted to enable clathrin light chain binding activity and signaling receptor binding activity. Involved in several processes, including amyloid precursor protein metabolic process; neurotransmitter receptor transport; and receptor recycling. Located in several cellular components, including glutamatergic synapse; late endosome; and lateral plasma membrane. Is expressed in several structures, including central nervous system; genitourinary system; gut; peripheral nervous system ganglion; and sensory organ. Orthologous to human NSG1 (neuronal vesicle trafficking associated 1). [provided by Alliance of Genome Resources, Apr 2022]
