Summary: Predicted to enable DNA-binding transcription factor 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 embryonic retina morphogenesis in camera-type eye; midbrain development; and striated muscle cell differentiation. Predicted to be active in nucleus. Orthologous to human PBX2 (PBX homeobox 2). [provided by Alliance of Genome Resources, Nov 2024]

These data define a novel role for Pbx2 in patterning the vertebrate retina and tectum in a manner required for proper retinal ganglion cell axon outgrowth

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.
