    Summary
    Enables aralkylamine N-acetyltransferase activity and arylamine N-acetyltransferase activity. Involved in catecholamine metabolic process and chitin-based cuticle sclerotization. Located in cytoplasm. Is expressed in several structures, including adult central brain astrocyte-like glial cell; brain; gut section; neurons; and presumptive embryonic/larval system.
