CC -!- FUNCTION: Serotonin transporter whose primary function in the central
CC nervous system involves the regulation of serotonergic signaling via
CC transport of serotonin molecules from the synaptic cleft back into the
CC pre-synaptic terminal for re-utilization. Plays a key role in mediating
CC regulation of the availability of serotonin to other receptors of
CC serotonergic systems. Terminates the action of serotonin and recycles
CC it in a sodium-dependent manner (By similarity). {ECO:0000250,
CC ECO:0000269|PubMed:8601815}.
CC -!- SUBUNIT: Monomer or homooligomer (By similarity). Interacts (via C-
CC terminus) with SCAMP2; the interaction is direct and retains
CC transporter molecules intracellularly. Interacts with filamentous actin
CC and STX1A (By similarity). Interacts with SEC23A, SEC24C and PATJ.
CC Interacts with NOS1; the interaction may diminish the cell surface
CC localization of SERT in the brain and, correspondingly, reduce
CC serotonin reuptake. Interacts with TGFB1I1 (By similarity). Interacts
CC with ITGAV:ITGB3 (By similarity). {ECO:0000250|UniProtKB:P31645,
CC ECO:0000250|UniProtKB:P31652, ECO:0000250|UniProtKB:Q60857}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q60857};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:Q7K4Y6}.
CC Endomembrane system {ECO:0000250|UniProtKB:P31652}; Multi-pass membrane
CC protein {ECO:0000255}. Endosome membrane
CC {ECO:0000250|UniProtKB:P31652}; Multi-pass membrane protein
CC {ECO:0000255}. Synapse {ECO:0000250|UniProtKB:Q60857}. Cell junction,
CC focal adhesion {ECO:0000250|UniProtKB:Q60857}. Note=Could be part of
CC recycling endosomes. Density of transporter molecules on the plasma
CC membrane is itself regulated by STX1A. Density of transporter molecules
CC on the plasma membrane is also regulated by serotonin (By similarity).
CC Density of transporter molecules seems to be modulated by ITGAV:ITGB3
CC (By similarity). {ECO:0000250|UniProtKB:P31645,
CC ECO:0000250|UniProtKB:P31652, ECO:0000250|UniProtKB:Q60857}.
CC -!- PTM: Phosphorylation at Thr-276 increases 5-HT uptake and is required
CC for cGMP-mediated SERT regulation. {ECO:0000250|UniProtKB:P31645}.
CC -!- MISCELLANEOUS: This protein is the target of psychomotor stimulants
CC such as amphetamines or cocaine.
CC -!- SIMILARITY: Belongs to the sodium:neurotransmitter symporter (SNF) (TC
CC 2.A.22) family. SLC6A4 subfamily. {ECO:0000305}.
