The
serotonin transporter (
SERT or
5-HTT) also known as the
sodium-dependent serotonin transporter and
solute carrier family 6 member 4 is a
protein that in humans is encoded by the
SLC6A4 gene. SERT is a type of
monoamine transporter protein that
transports serotonin from the
synaptic cleft to the presynaptic neuron.
