Summary
Predicted to enable choline transmembrane transporter activity and creatine:sodium symporter activity. Predicted to be involved in sodium ion transmembrane transport. Predicted to act upstream of or within creatine transmembrane transport. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be integral component of plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study creatine transporter deficiency. Human ortholog(s) of this gene implicated in creatine transporter deficiency and intellectual disability. Orthologous to human SLC6A8 (solute carrier family 6 member 8).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
