Summary: Predicted to enable protein homodimerization activity. Involved in several processes, including determination of adult lifespan; follicle cell of egg chamber development; and nervous system development. Located in cytosol. Is expressed in several structures, including Kenyon cell; ganglia; larval imaginal tissue; larval multidendritic neurons; and salivary gland. Orthologous to several human genes including TSC22D1 (TSC22 domain family member 1). [provided by Alliance of Genome Resources, Dec 2024]
