Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Acts upstream of or within inferior colliculus development; negative regulation of neuron apoptotic process; and positive regulation of transcription by RNA polymerase II. Part of transcription regulator complex. Is expressed in several structures, including brain; ganglia; genitourinary system; heart; and retina. Orthologous to human TFAP2D (transcription factor AP-2 delta). [provided by Alliance of Genome Resources, Apr 2022]
