Enables DNA binding activity and promoter-specific chromatin binding activity. Acts upstream of or within several processes, including G1/S transition of mitotic cell cycle; hepatocyte differentiation; and regulation of DNA binding activity. Located in nucleus. Is expressed in several structures, including blastocyst; embryo mesenchyme; gut; nervous system; and sensory organ epithelium. Orthologous to human TAF10 (TATA-box binding protein associated factor 10). [provided by Alliance of Genome Resources, Apr 2022]
