Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including central nervous system development; embryonic skeletal system morphogenesis; and regionalization. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; embryo ectoderm; embryo mesenchyme; metanephros; and nervous system. Orthologous to human HOXB2 (homeobox B2). [provided by Alliance of Genome Resources, Dec 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.
