Summary: Predicted to enable several functions, including DNA binding activity; NF-kappaB binding activity; and nuclease activity. Acts upstream of or within cell redox homeostasis. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; autopod; early conceptus; nervous system; and sensory organ.

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.
