The function of Ensembl gene identifier ENSG00000167654 (ATCAY, ATCAY kinesin light chain interacting caytaxin) is as follows. Functions in the development of neural tissues, particularly the postnatal maturation of the cerebellar cortex. May play a role in neurotransmission through regulation of glutaminase/GLS, an enzyme responsible for the production in neurons of the glutamate neurotransmitter. Alternatively, may regulate the localization of mitochondria within axons and dendrites. .
