Anti-trafficking protein particle complex subunit 8 antibodies are used for the immunodetection of the protein encoded by the TRAPPC8 gene. In humans, the canonical protein has a reported length of 1435 amino acid residues and a mass of 161 kDa. Its subcellular localization is in the Golgi. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the TRS85 protein family, it is reported to play a role in endoplasmic reticulum to Golgi apparatus trafficking at a very early stage. Other names for this target antigen include HsT2706, KIAA1012, TRS85, general sporulation gene 1 homolog, protein TRS85 homolog, and GSG1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
