Summary: Enables choline binding activity and choline transmembrane transporter activity. Acts upstream of or within several processes, including acetylcholine biosynthetic process; chemical synaptic transmission; and choline transport. Located in neuronal cell body and plasma membrane. Is expressed in several structures, including central nervous system and diaphragm. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 20 and distal hereditary motor neuronopathy type 7A. Orthologous to human SLC5A7 (solute carrier family 5 member 7).

What's a GeneRIF?

Our findings suggest that CHT protein levels preferentially impact the capacity for ACh release afforded by mobilization of reserve pool vesicles
Title: Differential impact of genetically modulated choline transporter expression on the release of endogenous versus newly synthesized acetylcholine.
These data provide evidence for an epithelium-independent non-vesicular, non-quantal ACh release in the mouse trachea involving low-affinity choline transporters.
Title: Cholinergic activation of the murine trachealis muscle via non-vesicular acetylcholine release involving low-affinity choline transporters.
bacterial artificial chromosome CHT mice thus represent a novel tool to examine both the positive and negative impact of constitutively elevated cholinergic signaling capacity
Title: Transgenic overexpression of the presynaptic choline transporter elevates acetylcholine levels and augments motor endurance.
These findings reveal compensatory mechanisms that, in the context of moderate cognitive challenges, can overcome the performance deficits expected from the significantly reduced ACh capacity of CHT+/- cholinergic terminals.
Title: Monitoring cholinergic activity during attentional performance in mice heterozygous for the choline transporter: a model of cholinergic capacity limits.
CHT association with cholesterol-rich rafts is critical for its function
Title: Regulation of the high-affinity choline transporter activity and trafficking by its association with cholesterol-rich lipid rafts.
This study showed that a constitutive loss of CHT expression in hemizygous mice leads to a significant reduction in basal extracellular dopamine levels in the nucleus accumbens.
Title: Choline transporter hemizygosity results in diminished basal extracellular dopamine levels in nucleus accumbens and blunts dopamine elevations following cocaine or nicotine.
This study demonistrated that CHT support for neuromuscular signaling involves contributions to ACh synthesis as well as cholinergic synaptic vesicle availability.
Title: Motor neuron-specific overexpression of the presynaptic choline transporter: impact on motor endurance and evoked muscle activity.
CHT1 knockout mice have tachycardia and hypertension at rest.
Title: Tachycardia, reduced vagal capacity, and age-dependent ventricular dysfunction arising from diminished expression of the presynaptic choline transporter.
Synapses persist for at least 2-3 months without postsynaptic activity; however, the presynaptic terminals lack high-affinity choline transporters (CHTs), and as a result, they are quickly depleted of transmitter.
Title: An activity-dependent retrograde signal induces the expression of the high-affinity choline transporter in cholinergic neurons.
adaptor proteins have important functions for CHT trafficking in neuronal cells

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.
