Summary: Enables deoxyribonuclease II activity. Acts upstream of or within DNA catabolic process; enucleate erythrocyte differentiation; and regulation of immune response. Predicted to be located in lysosome. Is expressed in liver; olfactory epithelium; and vibrissa. Used to study rheumatoid arthritis. Orthologous to human DNASE2 (deoxyribonuclease 2, lysosomal).

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.
