Summary: Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; p53 binding activity; and promoter-specific chromatin binding activity. Involved in several processes, including cellular response to estradiol stimulus; regulation of DNA-templated transcription; and regulation of neuron projection development. Acts upstream of or within several processes, including axonogenesis; neuromuscular process controlling balance; and sensory perception of sound. Located in cytoplasm; euchromatin; and nucleus. Is expressed in several structures, including central nervous system; glomerular tuft; placenta; somite; and visual system. Orthologous to human POU4F2 (POU class 4 homeobox 2).

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.
