Entrez Gene Summary for SLC22A5 Gene

  • Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. The encoded protein is a plasma integral membrane protein which functions both as an organic cation transporter and as a sodium-dependent high affinity carnitine transporter. The encoded protein is involved in the active cellular uptake of carnitine. Mutations in this gene are the cause of systemic primary carnitine deficiency (CDSP), an autosomal recessive disorder manifested early in life by hypoketotic hypoglycemia and acute metabolic decompensation, and later in life by skeletal myopathy or cardiomyopathy.

GeneCards Summary for SLC22A5 Gene

SLC22A5 (Solute Carrier Family 22 (Organic Cation/Carnitine Transporter), Member 5) is a Protein Coding gene. Diseases associated with SLC22A5 include visceral steatosis and carnitine deficiency, systemic primary. Among its related pathways are Regulation of Cholesterol Biosynthesis by SREBP (SREBF) and Glucose / Energy Metabolism. GO annotations related to this gene include PDZ domain binding and drug transmembrane transporter activity. An important paralog of this gene is SLC22A12.

UniProtKB/Swiss-Prot for SLC22A5 Gene

  • Sodium-ion dependent, high affinity carnitine transporter. Involved in the active cellular uptake of carnitine. Transports one sodium ion with one molecule of carnitine. Also transports organic cations such as tetraethylammonium (TEA) without the involvement of sodium. Also relative uptake activity ratio of carnitine to TEA is 11.3.
