Anti-Tektin 2 antibodies are used in the immunodetection of the protein encoded by the TEKT2 gene. In humans, the canonical protein has a reported length of 430 amino acid residues and a mass of 49.7 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed at high levels in testis, trachea and fetal lung, and at lower levels in ovary, pituitary, adult lung, fetal brain and fetal kidney. A member of the Tektin protein family, it is a known microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia and flagellar axoneme. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include TEKTIN-T, h-tektin-t, tektin 2 (testicular), tektin-B1, testicular tektin B1-like protein, and TEKTB1.
