CC -!- FUNCTION: Transmembrane transporter that imports choline from the
CC extracellular space to the neuron with high affinity. Choline uptake is
CC the rate-limiting step in acetylcholine synthesis. Sodium ion- and
CC chloride ion-dependent. {ECO:0000269|PubMed:10649566}.
CC -!- SUBUNIT: Homooligomerizes at cell surface (By similarity). Interacts
CC with SEC14L1; may regulate SLC5A7 (PubMed:17092608).
CC {ECO:0000250|UniProtKB:Q9GZV3, ECO:0000269|PubMed:17092608}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:Q9GZV3}; Multi-
CC pass membrane protein {ECO:0000250|UniProtKB:Q9GZV3}. Cell membrane
CC {ECO:0000250|UniProtKB:Q9GZV3}. Synapse {ECO:0000250|UniProtKB:Q9GZV3}.
CC Note=Localized at the neuromuscular junction.
CC {ECO:0000250|UniProtKB:Q9GZV3}.
CC -!- TISSUE SPECIFICITY: Expressed in basal forebrain, brain stem, spinal
CC chord, and striatum. Specific for cholinergic neurons.
CC {ECO:0000269|PubMed:10649566}.
CC -!- PTM: Phosphorylated. {ECO:0000250}.
CC -!- MISCELLANEOUS: Specifically inhibited by nanomolar concentrations of
CC hemicholinium 3.
CC -!- SIMILARITY: Belongs to the sodium:solute symporter (SSF) (TC 2.A.21)
CC family. {ECO:0000305}.
