Summary: Predicted to enable DNA binding activity and DNA-binding transcription factor activity, RNA polymerase II-specific. Acts upstream of or within several processes, including cardiac muscle tissue regeneration; cranial skeletal system development; and regulation of cardiac muscle cell proliferation. Predicted to be located in nucleus. Is expressed in several structures, including mesenchyme; pectoral fin bud; pectoral fin field; pharyngeal arch; and pleuroperitoneal region. 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, Jan 2025]

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.
