Background: VMAT2

The Vesicular Monoamine Transporter 2 (VMAT2), also known as VAT2 and SCL18A, is a 55-75 kDa member of the vesicular transporter family, a major facilitator superfamily. VMAT2 is a 12 transmembrane (TM) glycoprotein that is found in the membrane of brain neurosecretory vesicles. It transports monoamines (dopamine, serotonin, and particularly histamine) from the cytosol into secretion vesicles by exchanging two H⁺ ions for one molecule of amine. Human VMAT2 is 514 amino acids (aa) in length. It contains two cytoplasmic domains, a 20 aa and a 52 aa N- and C-terminal respectively, plus an extended 88 aa luminal loop between aa 42-129. There is one luminal, intrachain disulfide bond that contributes to amine transport (C126-C333). In addition, residues in TM domains 5-8 (aa 220-352) and 9-12 (aa 358‑462) also contribute to high affinity ligand interaction. VMAT2 is constitutively phosphorylated by CKII on S511 and S513. Within the cytoplasmic C-terminus, human VMAT2 is 94% aa identical to rat VMAT2.
