Mediates sodium- and chloride-dependent transport of dopamine (By similarity). Also mediates sodium- and chloride-dependent transport of norepinephrine (also known as noradrenaline) (By similarity). Regulator of light-dependent retinal hyaloid vessel regression, downstream of OPN5 signaling (By similarity).
Subcellular locations: Cell membrane, Cell projection, Neuron projection, Cell projection, Axon
Localizes to neurite tips in neuronal cells (By similarity). Colocalizes with SEPTIN4 at axon terminals, especially at the varicosities (By similarity).
