Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and chromatin binding activity. Involved in positive regulation of transcription, DNA-templated. Acts upstream of or within keratinocyte development; positive regulation of fibroblast proliferation; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; skeleton; skin; and telencephalon. Used to study idiopathic pulmonary fibrosis and systemic scleroderma. Orthologous to human FOSL2 (FOS like 2, AP-1 transcription factor subunit). [provided by Alliance of Genome Resources, Apr 2022]
