== Disease ==
[https://www.uniprot.org/uniprot/SC5A7_HUMAN SC5A7_HUMAN] Distal hereditary motor neuropathy type 7;Presynaptic congenital myasthenic syndromes. The disease is caused by variants affecting the gene represented in this entry.  The disease is caused by variants affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/SC5A7_HUMAN SC5A7_HUMAN] High-affinity Na(+)-coupled choline transmembrane symporter (PubMed:11027560, PubMed:11068039, PubMed:12237312, PubMed:12969261, PubMed:17005849, PubMed:23132865, PubMed:23141292, PubMed:27569547). Functions as an electrogenic, voltage-dependent transporter with variable charge/choline stoichiometry (PubMed:17005849). Choline uptake and choline-induced current is also Cl(-)-dependent where Cl(-) is likely a regulatory ion rather than cotransported ion (PubMed:11068039, PubMed:12237312, PubMed:17005849). Plays a critical role in acetylcholine (ACh) synthesis by taking up the substrate choline from the synaptic cleft into the presynaptic nerve terminals after neurotransmitter release (PubMed:27569547). SLC5A7/CHT1-mediated choline high-affinity transport in cholinergic neurons is the rate-limiting step for production of ACh, thereby facilitating communication by subsequent action potentials (PubMed:11027560). Localized predominantly in presynaptic terminal intracellular organelles, and translocated to the plasma membrane in active form in response to neuronal activity (PubMed:12969261, PubMed:15953352).<ref>PMID:11027560</ref> <ref>PMID:11068039</ref> <ref>PMID:12237312</ref> <ref>PMID:12969261</ref> <ref>PMID:15953352</ref> <ref>PMID:17005849</ref> <ref>PMID:23132865</ref> <ref>PMID:23141292</ref> <ref>PMID:27569547</ref>
