Also known as: cg6781; CG6781; Dmel\CG6781; dmgsto1; DmGSTO4; GSTO1; GSTO4; Sepia
Summary: Enables several functions, including glutathione dehydrogenase (ascorbate) activity; glutathione transferase activity; and protein homodimerization activity. Involved in eye pigment biosynthetic process; glutathione metabolic process; and pteridine biosynthetic process. Predicted to be active in cytoplasm. Is expressed in adult head and eye. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; and asthma. Orthologous to human GSTO1 (glutathione S-transferase omega 1) and GSTO2 (glutathione S-transferase omega 2). [provided by Alliance of Genome Resources, Dec 2024]
