Predicted to enable G protein-coupled serotonin receptor activity and neurotransmitter receptor activity. Involved in cerebral cortex cell migration and positive regulation of TOR signaling. Located in cilium. Is expressed in cerebral cortex intermediate zone; cerebral cortex subventricular zone; and cortical plate. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human HTR6 (5-hydroxytryptamine receptor 6). [provided by Alliance of Genome Resources, Apr 2022]
