Anti-Tsbp antibodies enable researchers to detect and measure the Tsbp antigen in biological samples. This target is a reported synonym of the CTR9 gene, which encodes CTR9 homolog, Paf1/RNA polymerase II complex component. This protein is known to function in the cellular response to lipopolysaccharides and chromatin organization, among other biological roles. The human version of Tsbp has a canonical amino acid length of 1173 residues and a protein mass of 133.5 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
