This family consists of several eukaryotic Organic-Anion-Transporting Polypeptides (OATPs). Several have been identified mostly in human and rat. Different OATPs vary in tissue distribution and substrate specificity. Since the numbering of different OATPs in particular species was based originally on the order of discovery, similarly numbered OATPs in humans and rats did not necessarily correspond in function, tissue distribution and substrate specificity (in spite of the name, some OATPs also transport organic cations and neutral molecules). Thus, Tamai et al. initiated the current scheme of using digits for rat OATPs and letters for human ones. Prostaglandin transporter (PGT) proteins are also considered to be OATP family members. In addition, the methotrexate transporter OATK is closely related to OATPs. This family also includes several predicted proteins from Caenorhabditis elegans and Drosophila melanogaster. This similarity was not previously noted. Note: Members of this family are described (in the Swiss-Prot database) as belonging to the SLC21 family of transporters. Length = 582

The Organo Anion Transporter (OAT) Family (TC 2.A.60)Proteins of the OAT family catalyze the Na+-independent facilitated transport of organic anions such as bromosulfobromophthalein and prostaglandins as well as conjugated and unconjugated bile acids (taurocholate and cholate, respectively). These transporters have been characterized in mammals, but homologues are present in C. elegans and A. thaliana. Some of the mammalian proteins exhibit a high degree of tissue specificity. For example, the rat OAT is found at high levels in liver and kidney and at lower levels in other tissues. These proteins possess 10-12 putative a-helical transmembrane spanners. They may catalyze electrogenic anion uniport or anion exchange. Length = 633

>cd06174 MFS 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

This family of proteins transports nucleosides at a high affinity. The transport mechanism is driven by proton motive force. This family includes nucleoside permease NupG and xanthosine permease from E.Coli.
This model describes a tightly conserved subfamily of the larger family of sugar (and other) transporters described by pfam model pfam00083. Members of this subfamily include closely related forms SV2A and SV2B of synaptic vesicle protein from vertebrates and a more distantly related homolog (below trusted cutoff) from Drosophila melanogaster. Members are predicted to have two sets of six transmembrane helices.
