Summary: Involved in several processes, including intestinal epithelial structure maintenance; macroautophagy; and regulation of intracellular signal transduction. Located in cell junction and cytoplasm. Is expressed in several structures, including adult head; antennal anlage; central brain anlage; dorsal head epidermis anlage; and visual anlage. Used to study Parkinson's disease. Orthologous to several human genes including ATG9A (autophagy related 9A). [provided by Alliance of Genome Resources, Jan 2025]
