The UBF1 ELISA kits listed below utilize specific antibodies for the plate-based assay of UBF1 in various samples. UBF1 is another term for the UBTF gene, which encodes the protein, upstream binding transcription factor in humans. The target protein is known to recognize the ribosomal RNA gene promoter and activates transcription mediated by RNA polymerase I through cooperative interactions with the transcription factor SL1/TIF-IB complex. Structurally, the UBTF protein is 764 amino acid residues in length and 89.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. This protein is known to be phosphorylated. Other names for this target antigen include CONDBA, NOR-90, and UBF.
