Summary: Predicted to enable acetylcholine:proton antiporter activity and monoamine:proton antiporter activity. Involved in neurotransmitter loading into synaptic vesicle; positive regulation of neuromuscular junction development; and positive regulation of synaptic transmission. Located in cytoplasm and terminal bouton. Is active in cholinergic synapse. Is expressed in several structures, including esophagus; heart; nervous system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 21. Orthologous to human SLC18A3 (solute carrier family 18 member A3). [provided by Alliance of Genome Resources, Dec 2024]

Studied object recognition and spatial location in mice deficient for Vesicular Acetylcholine Transporter (VAChT) within interneurons of the striatum, found: impairment in home cage object recognition with a 15 min retention delay, but not with a 3 h retention delay; no on memory for the location of objects; sex differences in retention

VAChT overexpression increases acetylcholine at the synaptic cleft and accelerates aging of neuromuscular junctions. Data demonstrate that increasing levels of acetylcholine at the synaptic cleft promote degeneration of adult neuromuscular junction, contributing to age- and disease-related motor deficits.

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.
