Serotonin transporter (Wiki) 
This is an integral membrane protein that transports the neurotransmitter serotonin from synaptic spaces into presynaptic neurons. This transport of serotonin by the SERT protein terminates the action of serotonin and recycles it in a sodium-dependent manner."  
    "
The serotonin transporter removes serotonin from the synaptic cleft back into the synaptic boutons. Thus, it terminates the effects of serotonin and simultaneously enables its reuse by the presynaptic neuron.[1]"  
    "
Medical studies have shown that changes in serotonin transporter metabolism appear to be associated with many different phenomena, including alcoholism, clinical depression, obsessive-compulsive disorder (OCD), romantic love,[3] hypertension and generalized social phobia.[4]"

    "
As a key regulator of central serotonergic activity, dysfunction of the serotonin transporter (5-HTT) represents a potential mechanism mediating pathological aggression."  
    "
Deletion of the 5-HTT gene produces a reduction in aggressive behavior and home cage activity. Desensitization of 5-HT(1A/1B) receptor function may contribute to reduced aggression in 5-HTT KO mice."
