Anti-FRBZ1 antibodies enable researchers to detect and measure the FRBZ1 antigen in biological samples. This target is a reported synonym of the ZBTB41 gene, which encodes zinc finger and BTB domain containing 41. This protein is known to function in the regulation of transcription, among other biological roles. The human version of FRBZ1 has a canonical amino acid length of 909 residues and a protein mass of 105.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells.
