Summary: Predicted to enable several functions, including histone H3K9me/H3K9me2 demethylase activity; iron ion binding activity; and nuclear androgen receptor binding activity. Involved in male gonad development; positive regulation of gene expression; and response to hypoxia. Predicted to be located in cytoplasm; male germ cell nucleus; and nucleoplasm. Predicted to be part of histone deacetylase complex. Predicted to be active in chromatin. Human ortholog(s) of this gene implicated in cervical cancer and colon cancer. Orthologous to human KDM3A (lysine demethylase 3A). [provided by Alliance of Genome Resources, Jul 2025]

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.
