Involved in several processes, including cellular response to oxygen levels; positive regulation of cardiac muscle cell apoptotic process; and spermatogenesis. Predicted to be located in cytoplasm; euchromatin; and nuclear speck. Predicted to be part of transcription regulator complex. 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.
