== Disease ==
[https://www.uniprot.org/uniprot/VMAT2_HUMAN VMAT2_HUMAN] Brain dopamine-serotonin vesicular transport disease. The disease is caused by variants affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/VMAT2_HUMAN VMAT2_HUMAN] Electrogenic antiporter that exchanges one cationic monoamine with two intravesicular protons across the membrane of secretory and synaptic vesicles. Uses the electrochemical proton gradient established by the V-type proton-pump ATPase to accumulate high concentrations of monoamines inside the vesicles prior to their release via exocytosis. Transports a variety of catecholamines such as dopamine, adrenaline and noradrenaline, histamine, and indolamines such as serotonin (PubMed:23363473, PubMed:8643547). Regulates the transvesicular monoaminergic gradient that determines the quantal size. Mediates somatodendritic dopamine release in hippocampal neurons, likely as part of a regulated secretory pathway that integrates retrograde synaptic signals (By similarity). Acts as a primary transporter for striatal dopamine loading ensuring impulse-dependent release of dopamine at the synaptic cleft (By similarity). Responsible for histamine and serotonin storage and subsequent corelease from mast cell granules (By similarity) (PubMed:8860238).[UniProtKB:Q01827][UniProtKB:Q8BRU6]<ref>PMID:23363473</ref> <ref>PMID:8643547</ref> <ref>PMID:8860238</ref>
