Summary
Enables DNA-binding transcription activator activity; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including His-Purkinje system development; energy homeostasis; and regulation of transcription by RNA polymerase II. Acts upstream of or within kidney development; mesoderm development; and regulation of neuron differentiation. Located in axon; cytoplasm; and nucleus. Is expressed in several structures, including central nervous system; genitourinary system; heart; limb; and sensory organ. Orthologous to human IRX3 (iroquois homeobox 3).

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) uses an alternate splice site in the 3' coding region, which results in a frameshift, compared to variant 1. It encodes isoform 2, which has a shorter and distinct C-terminus, compared to isoform 1.
