Enables DNA binding activity. Involved in lipid homeostasis and positive regulation of transcription from RNA polymerase II promoter by glucose. Acts upstream of or within lactation; positive regulation of transcription, DNA-templated; and regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including central nervous system; dorsal root ganglion; early conceptus; genitourinary system; and sensory organ. Orthologous to human USF2 (upstream transcription factor 2, c-fos interacting). [provided by Alliance of Genome Resources, Apr 2022]
