    Summary
    Enables creatine:sodium symporter activity. Predicted to be involved in several processes, including creatine transmembrane transport; protein catabolic process; and sodium ion transmembrane transport. Predicted to be located in apical plasma membrane. Predicted to be active in glutamatergic synapse and postsynaptic membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study cerebral creatine deficiency syndrome 1. Human ortholog(s) of this gene implicated in cerebral creatine deficiency syndrome 1 and intellectual disability. Orthologous to human SLC6A8 (solute carrier family 6 member 8). [provided by Alliance of Genome Resources, Nov 2024]

    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.
