Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in lens development in camera-type eye; nervous system development; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within locomotory behavior; neuron development; and regulation of gene expression. Located in nucleus. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and musculoskeletal system. Used to study Parkinson's disease and anterior segment dysgenesis. Human ortholog(s) of this gene implicated in anterior segment dysgenesis; anterior segment dysgenesis 1; cataract; cataract 11 multiple types; and cataract 9 multiple types. Orthologous to human PITX3 (paired like homeodomain 3). [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.
