Summary: Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; HMG box domain binding activity; and RNA polymerase II general transcription initiation factor activity. Involved in negative regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including embryonic morphogenesis; neuronal stem cell population maintenance; and positive regulation of cell population proliferation. Located in nucleus. Is expressed in several structures, including brain; embryo mesenchyme; genitourinary system; heart and pericardium; and sensory organ. Human ortholog(s) of this gene implicated in agnathia-otocephaly complex. Orthologous to human PRRX1 (paired related homeobox 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
