Anti-ZRANB3 antibodies are used in the immunodetection of the protein zinc finger RANBP2-type containing 3. In humans, the canonical protein has a reported length of 1079 amino acid residues and a mass of 123.2 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of the SNF2/RAD54 helicase protein family, it is known to be involved with DNA damage pathways and DNA repair. Synonyms for this target antigen include annealing helicase 2, zinc finger Ran-binding domain-containing protein 3, zinc finger, RAN-binding domain containing 3, and DNA annealing helicase and endonuclease ZRANB3.
