    Summary
    Predicted to enable deoxyribonuclease inhibitor activity; protein domain specific binding activity; and protein folding chaperone. Predicted to be involved in chaperone-mediated protein folding; negative regulation of deoxyribonuclease activity; and negative regulation of execution phase of apoptosis. Predicted to act upstream of or within negative regulation of apoptotic DNA fragmentation; positive regulation of apoptotic process; and thymocyte apoptotic process. Predicted to be located in several cellular components, including chromatin; cytosol; and nucleus. Predicted to be part of protein-containing complex. Orthologous to human DFFA (DNA fragmentation factor subunit alpha). [provided by Alliance of Genome Resources, Jan 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.
