Anti-TIP-1 antibodies enable researchers to detect and measure the TIP-1 antigen in biological samples. This target is a reported synonym of the TAX1BP3 gene, which encodes Tax1 binding protein 3. This protein is known to function in GTPase activation and the regulation of cell proliferation, among other biological roles. The human version of TIP-1 has a canonical amino acid length of 124 residues and a protein mass of 13.7 kilodaltons. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells and notably expressed in many tissues, such as the cervix, vagina, and adrenal gland.
