Summary: Enables aspartate 1-decarboxylase activity. Involved in visual behavior. Is expressed in adult head; dorsal medial indirect flight muscle cell; lamina; and muscle cell of mesothoracic extracoxal depressor muscle 66. Orthologous to several human genes including CSAD (cysteine sulfinic acid decarboxylase). [provided by Alliance of Genome Resources, Apr 2022]
