General annotation (Comments)

Function

Involved in the ATP-dependent vesicular transport of biogenic amine neurotransmitters. Pumps cytosolic monoamines including dopamine, norepinephrine, serotonin, and histamine into synaptic vesicles. Requisite for vesicular amine storage prior to secretion via exocytosis.

Subunit structure

Interacts with SLC6A3 By similarity.

Subcellular location

Cytoplasmic vesicle membrane; Multi-pass membrane protein.

Tissue specificity

Brainstem and stomach.

Sequence similarities

Belongs to the major facilitator superfamily. Vesicular transporter family.
