Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including memory; midbrain dopaminergic neuron differentiation; and olfactory behavior. Acts upstream of or within several processes, including negative regulation of neuron differentiation; nervous system development; and regulation of cell growth. Predicted to be active in nucleus. Is expressed in several structures, including brain; ear; embryo ectoderm; genitourinary system; and notochord. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 7. Orthologous to human LMX1A (LIM homeobox transcription factor 1 alpha).
