Predicted to enable protein C-terminus binding activity. Involved in negative regulation of L-glutamate import across plasma membrane. Acts upstream of or within with a negative effect on L-glutamate import across plasma membrane and protein localization to plasma membrane. Acts upstream of or within several processes, including L-glutamate transmembrane transport; glutathione metabolic process; and neuron death in response to oxidative stress. Located in plasma membrane. Is expressed in cerebral cortex subventricular zone; cerebral cortex ventricular layer; and cortical plate. Orthologous to human ARL6IP5 (ADP ribosylation factor like GTPase 6 interacting protein 5). [provided by Alliance of Genome Resources, Apr 2022]
