Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within embryonic skeletal system development; positive regulation of myotome development; and regulation of somitogenesis. Predicted to be active in nucleus. Is expressed in several structures, including embryo mesenchyme; genitourinary system; limb; oral epithelium; and thymus primordium. Orthologous to human DMRT2 (doublesex and mab-3 related transcription factor 2). [provided by Alliance of Genome Resources, Apr 2022]
