Anti-SNTN antibodies are used in the immunodetection of the protein sentan, cilia apical structure protein. In humans, the canonical protein has a reported length of 147 amino acid residues and a mass of 16.5 kDa. Its subcellular localization is in the cell projections. It is notably expressed in the nasopharynx, fallopian tube, endometrium, and bronchus. A member of the S-100 protein family, SNTN is believed to be a component of the linker structure that bridges the ciliary membrane and peripheral singlet microtubules. Synonyms for this target antigen include sentan and S100A-like protein. SNTN gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. These SNTN antibodies are widely used in Immunohistochemistry experiments, among other applications.
