Summary: Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including imaginal disc pattern formation; imaginal disc-derived appendage morphogenesis; and positive regulation of macromolecule biosynthetic process. Located in nucleus. Is expressed in several structures, including ganglia; imaginal disc; larval external muscle cell; optic lobe intrinsic columnar neurons; and organism subdivision. Orthologous to human LHX2 (LIM homeobox 2) and LHX9 (LIM homeobox 9). [provided by Alliance of Genome Resources, Dec 2024]
