Anti-tubulin tyrosine ligase-like family member 12 antibodies enable researchers to detect and measure the tubulin tyrosine ligase-like family member 12 antigen in biological samples. This target is a reported synonym of the TTLL12 gene, which encodes tubulin tyrosine ligase like 12. This protein is known to function in innate immune responses, among other biological roles. The human version of tubulin tyrosine ligase-like family member 12 has a canonical amino acid length of 644 residues and a protein mass of 74.4 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the kidney and prostate. Other names for this target antigen include dJ526I14.2, tubulin--tyrosine ligase-like protein 12, and inactive tubulin--tyrosine ligase-like protein 12.
