Anti-VMAT1/SLC18A1 Antibody Picoband® Fluoro488 Conjugated

Chromaffin granule amine transporter is a protein that in humans is encoded by the SLC18A1 gene. This gene is mapped to 8p21.3. The vesicular monoamine transporter acts to accumulate cytosolic monoamines into vesicles, using the proton gradient maintained across the vesicular membrane. Its proper function is essential to the correct activity of the monoaminergic systems that have been implicated in several human neuropsychiatric disorders. The transporter is a site of action of important drugs, including reserpine and tetrabenazine.

Highly expressed in chromaffin cells of the adrenal medulla (at protein level) . Detected in peripheral sympathetic ganglia (at protein level) . Found in some paracrine cells in stomach and duodenum (at protein level) .

Involved in the transport of biogenic monoamines, such as serotonin, from the cytoplasm into the secretory vesicles of neuroendocrine and endocrine cells.
