Name Solute carrier family 22 member 16
Synonyms
  1. CT2
  2. Carnitine transporter 2
  3. FLIPT2
  4. Flipt 2
  5. Fly-like putative transporter 2
  6. Organic cation transporter OKB1
  7. Organic cation/carnitine transporter 6
Gene Name SLC22A16
Protein Type Transporter
Biological Properties
General Function Involved in transporter activity
Specific Function High affinity carnitine transporter; the uptake is partially sodium-ion dependent. Thought to mediate the L-carnitine secretion mechanism from testis epididymal epithelium into the lumen which is involved in the maturation of spermatozoa. Also transports organic cations such as tetraethylammonium (TEA) and doxorubicin. The uptake of TEA is inhibited by various organic cations. The uptake of doxorubicin is sodium-independent
