Summary: Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in cochlea morphogenesis and negative regulation of mesenchymal cell apoptotic process. Acts upstream of or within forebrain neuron differentiation; inner ear development; and sensory perception of sound. Predicted to be located in nucleoplasm. Is expressed in several structures, including brain; cranium; ear; embryo ectoderm; and foregut-midgut junction. Human ortholog(s) of this gene implicated in X-linked deafness 2. Orthologous to human POU3F4 (POU class 3 homeobox 4). [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.
