Solute carrier family 46 member 2, also called Thymic stromal cotransporter protein, of the Major Facilitator Superfamily of transporters
Solute carrier family 46 member 2 (SLC46A2) is also called thymic stromal cotransporter protein (TSCOT). It is a putative 12-transmembrane protein mainly expressed in the thymic cortex in a specific thymic epithelial cell (TEC) subpopulation. Polymorphisms in TSCOT are linked to cervical cancer in affected sib-pairs with high mean age at diagnosis. TSCOT belongs to the Eukaryotic Solute carrier 46 (SLC46)/Bacterial Tetracycline resistance (TetA) -like (SLC46/TetA-like) family of the Major Facilitator Superfamily (MFS) of transporters. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
Feature 1:putative chemical substrate binding pocket [chemical binding site]
Evidence:
Comment:based on the structures of MFS transporters with bound substrates, substrate analogs, and/or inhibitors
Comment:since MFS proteins facilitate the transport of many different substrates including ions, sugar phosphates, drugs, neurotransmitters, nucleosides, amino acids, and peptides, the residues involved in substrate binding may not be strictly conserved among superfamily members
Comment:the substrate binding site or translocation pore has access to both sides of the membrane in an alternating fashion through a conformational change of the MFS transporter
