The SLC (solute carrier) Tables - originally prepared by the authors of the 2004 SLC review in Pflügers Archives - provide the latest updates on the SLC families and their members, as well as relevant links to gene databases and reviews in the literature.

The Human Genome Organization (HUGO) Gene Nomenclature Committee (HGNC) Database includes more than 45 transporter families of the SLC gene series. The SLC families represent a major portion of transporter-related genes, and additional SLC transporters are continually being identified.

The remaining transporter-related genes include those encoding ATP-driven transporters, channels, ionotropic receptors, aquaporins, transporter and channel subunits, auxiliary/regulatory transport proteins, etc. (see figure to the right).
