Anti-FP630 antibodies enable researchers to detect and measure the FP630 antigen in biological samples. This target is a reported synonym of the GTF2IRD2 gene, which encodes GTF2I repeat domain containing 2. The human version of FP630 has a canonical amino acid length of 949 residues and a protein mass of 107.2 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the nucleus of cells. FP630 is a member of the TFII-I protein family.
