MFSD4A
Major facilitator superfamily domain containing 4A is a protein belonging to the MFS Pfam clan. It is an atypical solute carrier, thus a plausible SLC transporter in humans. MFSD4A has been identified in both central and peripheral areas. References {{Reflist Solute carrier family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solute Carrier Family
The solute carrier (SLC) group of membrane transport proteins include over 400 members organized into 66 families. Most members of the SLC group are located in the cell membrane. The SLC gene nomenclature system was originally proposed by the HUGO Gene Nomenclature Committee (HGNC) and is the basis for the official HGNC names of the genes that encode these transporters. A more general transmembrane transporter classification can be found in TCDB, TCDB database. Solutes that are transported by the various SLC group members are extremely diverse and include both charged and uncharged organic molecules as well as inorganic ions and the gas Ammonia transporter, ammonia. As is typical of integral membrane proteins, SLCs contain a number of hydrophobic transmembrane Alpha helix, alpha helices connected to each other by hydrophilic intra- and extra-cellular loops. Depending on the SLC, these transporters are functional as either monomers or obligate homo- or hetero-oligomers. Many SLC fam ...

Atypical SLCs
Atypical Solute Carrier Families (Atypical SLCs) are novel plausible secondary active or facilitative transporter proteins that share ancestral background with the known solute carrier families (SLCs). However, they have not been assigned a name according to the SLC root system, or been classified into any of the existing SLC families. Atypical major facilitator superfamily transport families Most atypical SLCs are families within the major facilitator superfamily (MFS). These atypical SLCs are plausible secondary active or facilitative transporter proteins that share ancestry with the known solute carriers. They are, however, not named according to the SLC root system, or classified into any of the existing SLC families. Atypical MFS transporter families (ATMFs) are categorised based on their sequence similarity and phylogenetic closeness. Some Atypical SLC of MFS type are: OCA2, CLN3, SPNS1, SPNS2, SPNS3, SV2A, SV2B, SV2C, SVOP, SVOPL, MFSD1, MFSD2A, MFSD2B, MFSD3, ...

Major Facilitator Superfamily
The major facilitator superfamily (MFS) is a Protein superfamily, superfamily of membrane transport proteins that facilitate movement of small solutes across cell membranes in response to chemiosmosis, chemiosmotic gradients. Function The major facilitator superfamily (MFS) are membrane proteins which are expressed ubiquitously in all kingdoms of life for the import or export of target substrates. The MFS family was originally believed to function primarily in the uptake of sugars but subsequent studies revealed that drugs, metabolites, oligosaccharides, amino acids and oxyanions were all transported by MFS family members. These proteins energetically drive transport utilizing the electrochemical gradient of the target substrate (uniporter), or act as a cotransporter where transport is coupled to the movement of a second substrate. Fold The basic fold of the MFS transporter is built around 12, or in some cases, 14 transmembrane helix, transmembrane helices (TMH), with two 6- (o ...
