Editing Vesicular monoamine transporter (section)

===Animal research===
Current research related to VMAT uses VMAT2 knockout mice to explore the behavioral genetics of this transporter in an animal model. VMAT2 knockouts are known to be lethal as homozygotes, but heterozygote knockouts are not lethal and are used in many studies as a durable animal model.<ref name="Wimalasena, K. 2010"/><ref name="Lawal HO 2013"/>

From knockout and knockdown mice, researchers have discovered that it is good to have over-expression or under-expression of the VMAT genes in some circumstances.<ref name="Lawal HO 2013"/> Mice are also used in drug studies, particularity studies involving the effect cocaine and methamphetamine have on VMATs.<ref name="Lawal HO 2013"/> Studies involving animals have prompted scientists to work on developing drugs that inhibit or enhance the function of VMATs. Drugs that inhibit VMATs may have use in addiction but further studies are needed.<ref name="Lawal HO 2013"/> Enhancing the function of VMATs may also have therapeutic value.<ref name="Lawal HO 2013"/>
