Summary
Predicted to enable 3'-5'-DNA exonuclease activity; 3'-5'-RNA exonuclease activity; and magnesium ion binding activity. Predicted to be involved in DNA metabolic process. Predicted to act upstream of or within nucleobase-containing compound metabolic process. Predicted to be located in focal adhesion; mitochondrion; and nucleolus. Predicted to be active in mitochondrion. Orthologous to human REXO2 (RNA exonuclease 2). [provided by Alliance of Genome Resources, Oct 2024]

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.
