Summary: Enables chromatin binding activity. Acts upstream of or within embryonic limb morphogenesis; positive regulation of transcription by RNA polymerase II; and proximal/distal pattern formation. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; eye; and genitourinary system. Orthologous to human PBX2 (PBX homeobox 2). [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.
