Expression of Cholinergic Markers and Characterization of Splice Variants during Ontogenesis of Rat Dorsal Root Ganglia Neurons.
Title: Expression of Cholinergic Markers and Characterization of Splice Variants during Ontogenesis of Rat Dorsal Root Ganglia Neurons.
VACHT is inserted into the presynaptic membrane during synaptic vesicles' exocytosis, removed during their endocytotic recycling, and plays a role in non-quantal secretion of acetylcholine.
Title: Increased non-quantal release of acetylcholine after inhibition of endocytosis by methyl-β-cyclodextrin: the role of vesicular acetylcholine transporter.
Sympathetic preganlionics segregate mENK from VAChT and ChAT; most of the subset of mENKergic varicosities negative for VAChT also do not express Syn, suggesting a different vesicular pattern in these sympathetic preganglionic varicosities.
Title: Segregation of met-enkephalin from vesicular acetylcholine transporter and choline acetyltransferase in sympathetic preganglionic varicosities mostly lacking synaptophysin and synaptotagmin.
results suggest that in rodent prefrontal cortex, the alpha7nAChR plays a major role in modulation of the postsynaptic excitation in spiny dendrites in contact with vesicular acetylcholine transporter containing axons

VAChT concentrations were increased in the brain of control SHR compared to age-matched normotensive Wistar-Kyoto rats.

During VAChT trafficking, the C-terminal dileucine-containing motif is sufficient as a dual signal for both internalization and synaptic vesicle targeting.

18.0 mg/kg dose of chlorpyrifos was associated with (brain region-dependent) decreases in nerve growth factor receptors and cholinergic proteins including the vesicular acetylcholine transporter

VAChT interacts with clathrin-associated adaptor complexes AP-1 and AP-2
Title: The vesicular acetylcholine transporter interacts with clathrin-associated adaptor complexes AP-1 and AP-2.
A model for VAChT is suggested in which the known ion pair between lysine in transmembrane domain(TMD)II and aspartate in TMDXI controls the conformation or relative position of TMDXI, which in turn controls additional TMDs in the VAChT carboxy-terminal.
Title: Mutational and pH analysis of ionic residues in transmembrane domains of vesicular acetylcholine transporter.

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.
