Anti-TTC39B antibodies are used in the immunodetection of the protein tetratricopeptide repeat domain 39B. In humans, the canonical protein has a reported length of 682 amino acid residues and a mass of 77 kDa. Up to 7 different isoforms have been reported for this protein. A member of the TTC39 protein family, TTC39B is reported to regulate high density lipoprotein (HDL) cholesterol metabolism by promoting the ubiquitination and degradation of the oxysterols receptors LXR (NR1H2 and NR1H3). Synonyms for this target antigen include tetratricopeptide repeat protein 39B and TPR repeat protein 39B. TTC39B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the TTC39B antibodies listed below. ELISA and Immunohistochemistry are also common applications.
