Summary: Predicted to enable DNA-binding transcription factor binding activity and transcription coactivator activity. Involved in several processes, including gastric emptying; imaginal disc-derived appendage morphogenesis; and locomotor rhythm. Predicted to be active in nucleus. Is expressed in several structures, including adult pacemaker neurons; brain; cuboidal/columnar epithelium; glial cell; and imaginal disc. Orthologous to human LMO1 (LIM domain only 1) and LMO3 (LIM domain only 3). [provided by Alliance of Genome Resources, Jan 2025]
