Anti-trafficking protein particle complex subunit 6B antibodies are used for the immunodetection of the protein encoded by the TRAPPC6B gene. In humans, the canonical protein has a reported length of 158 amino acid residues and a mass of 18 kDa. Its subcellular localization is in the ER and Golgi. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the TRAPP small subunits protein family, it is a known component of the transport protein particle (TRAPP) complex that may function in specific stages of inter-organelle traffic. The gene encoding this protein is implicated in Neurodevelopmental disorder with microcephaly, epilepsy, and brain atrophy. Other names for this target antigen include TRAPP complex subunit 6B and trafficking protein particle complex 6B. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
