Predicted to enable chromatin DNA binding activity and histone binding activity. Involved in several processes, including cellular response to cytokine stimulus; cellular response to lipopolysaccharide; and macrophage activation involved in immune response. Acts upstream of or within several processes, including bone mineralization; bone trabecula morphogenesis; and osteoclast fusion. Predicted to be active in nucleus. Is expressed in submandibular gland primordium and vibrissa. Orthologous to human SBNO2 (strawberry notch homolog 2). [provided by Alliance of Genome Resources, Apr 2022]
