Summary
Predicted to enable histone binding activity and histone chaperone activity. Involved in male gonad development and response to testosterone. Predicted to be located in chromatin; cytoplasm; and nucleus. Predicted to be part of protein-containing complex. Predicted to be active in nucleoplasm. Orthologous to human NASP (nuclear autoantigenic sperm protein). [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.
