Synonyms
  1. ET transporter
  2. Ergothioneine transporter
  3. Organic cation/carnitine transporter 1
Gene Name SLC22A4
Protein Type Transporter
Biological Properties
General Function Involved in ion transmembrane transporter activity
Specific Function Sodium-ion dependent, low affinity carnitine transporter. Probably transports one sodium ion with one molecule of carnitine. Also transports organic cations such as tetraethylammonium (TEA) without the involvement of sodium. Relative uptake activity ratio of carnitine to TEA is 1.78. A key substrate of this transporter seems to be ergothioneine (ET)
