Enables DNA binding activity and chromatin binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within synapse maturation and ureter development. Located in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in NFIA-related disorder. Orthologous to human NFIA (nuclear factor I A). [provided by Alliance of Genome Resources, Apr 2022]
