Anti-trafficking protein particle complex subunit 12 antibodies are used for the immunodetection of the protein encoded by the TRAPPC12 gene. In humans, the canonical protein has a reported length of 735 amino acid residues and a mass of 79.4 kDa. Its subcellular localization is in the nucleus and ER. It is a known component of the TRAPP complex, which is involved in endoplasmic reticulum to Golgi apparatus trafficking at a very early stage. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Encephalopathy. Other names for this target antigen include PEBAS, TTC-15, TTC15, TPR repeat protein 15, tetratricopeptide repeat domain 15, and CGI-87. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
