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 heart development. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; embryo ectoderm; heart; sensory organ; and skin. Orthologous to human IRX4 (iroquois homeobox 4).

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.
