Anti-TRNP antibodies enable researchers to detect and measure the TRNP antigen in biological samples. This target is a reported synonym of the TRNP1 gene, which encodes TMF1 regulated nuclear protein 1. This protein is known to function in the cell cycle and the regulation of cell proliferation, among other biological roles. The human version of TRNP has a canonical amino acid length of 227 residues and a protein mass of 23.5 kilodaltons. It is reported to be localized in the nucleus of cells.
