Serotonin transporter Recombinant Rabbit mAb (一抗) - WB | Bioss

SLC6A4

Sodium-dependent serotonin transporter

Monomer or homooligomer. Interacts with TGFB1I1. Interacts (via sialylated form) with MYH9. Interacts with SEC23A, SEC24C and INADL. 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 VIM. Interacts (via C-terminus) with SCAMP2; the interaction is direct and retains transporter molecules intracellularly. Interacts with RAB4 (GTP-bound form); the interaction retains transporter molecules intracellularly.

Cell membrane; Multi-pass membrane protein. Endomembrane system; Multi-pass membrane protein. Endosome membrane; Multi-pass membrane protein.

Expressed in platelets (at protein level).

Glycosylated; modification with sialylated N-glycans is a requirement for transporters to associate with each other and to function as homooligomeric forms (By similarity).
Phosphorylation at Thr-276 increases 5-HT uptake and is required for cGMP-mediated SERT regulation (By similarity). Phosphorylation upon PKC stimulation modifies the SERT distribution and density in the membrane, and diminishes the uptake capacity.

Belongs to the sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family. SLC6A4 subfamily.

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.
