Anti-KRBO3 antibodies enable researchers to detect and measure the KRBO3 antigen in biological samples. This target is a reported synonym of the ZNF534 gene, which encodes zinc finger protein 534. This protein is known to function in the regulation of transcription, among other biological roles. The human version of KRBO3 has a canonical amino acid length of 674 residues and a protein mass of 77.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. KRBO3 is a member of the Krueppel C2H2-type zinc-finger protein family.
