The TF1B ELISA kits listed below are analytical tools for measuring concentrations of TF1B in various samples. TF1B is an alternative name for the human TRIM28 gene, which encodes the protein, tripartite motif containing 28. It has been mentioned that TF1B plays a role in chromatin organization and DNA repair, among other functions. Structurally, the TRIM28 protein is 835 amino acid residues in length and 88.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be expressed in all tissues tested including spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocytes. This protein is known to be ubiquitinated, sumoylated and phosphorylated. Other names for this target antigen include KAP1, PPP1R157, and RNF96.
