Anti-TMSB15 antibodies enable researchers to detect and measure the TMSB15 antigen in biological samples. This target is a reported synonym of the TMSB15A gene, which encodes thymosin beta 15A. This protein is known to play an important role in the organization of the cytoskeleton. The human version of TMSB15 has a canonical amino acid length of 45 residues and a protein mass of 5.2 kilodaltons. It is reported to be localized in the cytoplasm of cells. TMSB15 is a member of the Thymosin beta protein family.
