Summary: Enables choline O-acetyltransferase activity and choline binding activity. Involved in several processes, including acetylcholine biosynthetic process; antral ovarian follicle growth; and response to ethanol. Predicted to be located in axon and neuronal cell body. Predicted to be active in cytoplasm and neuron projection. Used to study depressive disorder. Biomarker of Alzheimer's disease; asthma; and depressive disorder. Human ortholog(s) of this gene implicated in Alzheimer's disease and congenital myasthenic syndrome 6. Orthologous to human CHAT (choline O-acetyltransferase).

Higher choline acetyltransferase activity rostrally than caudally in the trapezoid body is consistent with evidence that the centrifugal cholinergic innervation of the cochlear nucleus derives predominantly from locations at or rostral to its anterior part, in the superior olivary complex and pontomesencephalic tegmentum.

Data show that choline acetyltransferase (ChAT) immunoreactivity is reduced in the basal forebrain of late adolescent rats (P56) that persists into later adulthood (P220) following exposure to a model of adolescent binge drinking.
Title: Adolescent, but not adult, binge ethanol exposure leads to persistent global reductions of choline acetyltransferase expressing neurons in brain.

In summary, our present study revealed a remarkable timing and topographic difference on the postnatal development of the nestin expression within the MS-DBB of BF compared with ChAT and PV expression.

Our results suggest that the differences in the expression level of PKA and ChAT (but not of CaMKIIalpha), as well as the differences in the activation of both PKA and CaMKIIalpha, may contribute to the individual variation in learning skills

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.
