Summaries for SLC6A18 Gene

Entrez Gene Summary for SLC6A18 Gene

  • The SLC6 family of proteins, which includes SLC6A18, act as specific transporters for neurotransmitters, amino acids, and osmolytes like betaine, taurine, and creatine. SLC6 proteins are sodium cotransporters that derive the energy for solute transport from the electrochemical gradient for sodium ions (Hoglund et al., 2005 [PubMed 16125675]).[supplied by OMIM, Apr 2010]

GeneCards Summary for SLC6A18 Gene

SLC6A18 (Solute Carrier Family 6 Member 18) is a Protein Coding gene. Diseases associated with SLC6A18 include Hartnup Disorder and Hyperglycinuria. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Amino acid transport across the plasma membrane. GO annotations related to this gene include neurotransmitter:sodium symporter activity. An important paralog of this gene is SLC6A19.
