Predicted to enable bile acid:sodium symporter activity. Predicted to be involved in bile acid and bile salt transport and regulation of neurotransmitter loading into synaptic vesicle. Predicted to act upstream of or within adult behavior and response to xenobiotic stimulus. Predicted to be located in plasma membrane. Predicted to be active in cholinergic synapse; dopaminergic synapse; and serotonergic synapse. Predicted to be integral component of synaptic vesicle membrane. Orthologous to human SLC10A4 (solute carrier family 10 member 4). [provided by Alliance of Genome Resources, Apr 2022]
