FAMILY

sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family

DESCRIPTION

Also known as SC6A4_HUMAN, SLC6A4, HTT, SERT. Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner. Monomer or homooligomer (By similarity). Interacts with TGFB1I1 (PubMed:16803896). Interacts with SEC23A, SEC24C and PATJ. Interacts with NOS1; the interaction may diminish the cell surface localization of SERT in the brain and, correspondingly, reduce serotonin reuptake. Interacts with filamentous actin and STX1A (By similarity). Interacts (via C-terminus) with SCAMP2; the interaction is direct and retains transporter molecules intracellularly (PubMed:16870614). Interacts with ITGAV:ITGB3 (By similarity).
