Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Involved in positive regulation of cold-induced thermogenesis and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including adipose tissue development; brown fat cell differentiation; and positive regulation of chromatin binding activity. Predicted to be located in nucleus. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; limb mesenchyme; and sensory organ. Orthologous to human EBF2 (EBF transcription factor 2). [provided by Alliance of Genome Resources, Apr 2022]
