Major Facilitator Superfamily; The Major Facilitator Superfamily (MFS) is a large and diverse group of secondary transporters that includes uniporters, symporters, and antiporters. MFS proteins facilitate the transport across cytoplasmic or internal membranes of a variety of substrates including ions, sugar phosphates, drugs, neurotransmitters, nucleosides, amino acids, and peptides. They do so using the electrochemical potential of the transported substrates. Uniporters transport a single substrate, while symporters and antiporters transport two substrates in the same or in opposite directions, respectively, across membranes. MFS proteins are typically 400 to 600 amino acids in length, and the majority contain 12 transmembrane alpha helices (TMs) connected by hydrophilic loops. The N- and C-terminal halves of these proteins display weak similarity and may be the result of a gene duplication/fusion event. Based on kinetic studies and the structures of a few bacterial superfamily members, GlpT (glycerol-3-phosphate transporter), LacY (lactose permease), and EmrD (multidrug transporter), MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement. Bacterial members function primarily for nutrient uptake, and as drug-efflux pumps to confer antibiotic resistance. Some MFS proteins have medical significance in humans such as the glucose transporter Glut4, which is impaired in type II diabetes, and glucose-6-phosphate transporter (G6PT), which causes glycogen storage disease when mutated.

Protein unc-93 homolog A and similar proteins of the Major Facilitator Superfamily of transporters; This subfamily is composed of Caenorhabditis elegans Uncoordinated protein 93 (also called putative potassium channel regulatory protein unc-93), human protein unc-93 homolog A (HmUnc-93A or UNC93A), and similar proteins. Unc-93 acts as a regulatory subunit of a multi-subunit potassium channel complex that may function in coordinating muscle contraction in C. elegans. The human UNC93A gene is located in a region of the genome that is frequently associated with ovarian cancer, however, there is no evidence that UNC93A has a tumor suppressor function. This unc93A-like subfamily 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.

Ion channel regulatory protein UNC-93; The proteins in this family are represented by UNC-93 from Caenorhabditis elegans and also includes protein unc-93 homolog A (UNC93A), protein unc-93 homolog B1 (UNC93B1), and UNC93-like protein MFSD11 (also called major facilitator superfamily domain- containing protein 11 or protein ET). UNC-93 colocalizes with SUP-10 and SUP-9 within muscle cells. UNC-93 acts as a regulatory subunit of a multi-subunit potassium channel complex that may function in coordinating muscle contraction in C. elegans. UNC93B1 controls intracellular trafficking and transport of a subset of Toll-like receptors (TLRs), including TLR3, TLR7 and TLR9, from the endoplasmic reticulum to endolysosomes where they can engage pathogen nucleotides and activate signaling cascades. 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.

Bacterial fucose permease, eukaryotic Major facilitator superfamily domain-containing protein 4, and similar proteins; This family is composed of bacterial L-fucose permease (FucP), eukaryotic Major facilitator superfamily domain-containing protein 4 (MFSD4) proteins, and similar proteins. L-fucose permease facilitates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell; it can also transport L-galactose and D-arabinose. The MFSD4 subfamily consists of two vertebrate members: MFSD4A and MFSD4B. The function of MFSD4A is unknown. MFSD4B is more commonly know as Sodium-dependent glucose transporter 1 (NaGLT1), a primary fructose transporter in rat renal brush-border membranes that also facilitates sodium-independent urea uptake. The FucP/MFSD4 family belongs to the Major Facilitator Superfamily (MFS) of membrane transport proteins, which are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
