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 camera-type eye development; hypothalamus development; and limb development. Predicted to be located in nucleus. Is expressed in several structures, including eye; genitourinary system; hemolymphoid system; nervous system; and neural ectoderm. Human ortholog(s) of this gene implicated in isolated microphthalmia 3. Orthologous to human RAX (retina and anterior neural fold homeobox). [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.
