UNC93-like Major facilitator superfamily domain-containing protein 11
This group is composed of UNC93-like protein MFSD11 (also called major facilitator superfamily domain-containing protein 11 or protein ET) and similar proteins, most of which are uncharacterized. MFSD11 is ubiquitously expressed in the periphery and the central nervous system of mice, where it is expressed in excitatory and inhibitory mouse brain neurons. Its expression is affected by altered energy homeostasis, suggesting plausible involvement in the energy regulation. MFSD11 belongs to the Unc-93 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
