Predicted to be involved in photoreceptor cell maintenance; regulation of autophagy; and visual perception. Predicted to be located in Golgi apparatus; apical plasma membrane; and photoreceptor inner segment. Predicted to be active in lysosome. Human ortholog(s) of this gene implicated in cone-rod dystrophy. Orthologous to human DRAM2 (DNA damage regulated autophagy modulator 2). [provided by Alliance of Genome Resources, Apr 2022]
