Anti-trafficking protein particle complex subunit 14 antibodies are used for the immunodetection of the protein encoded by the TRAPPC14 gene. In humans, the canonical protein has a reported length of 580 amino acid residues and a mass of 62.6 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is widely expressed across many tissue types. It is reported to be a specific subunit of the TRAPP (transport protein particle) II complex, a highly conserved vesicle tethering complex that functions in late Golgi trafficking as a membrane tether. The gene encoding this protein is implicated in Microcephaly. Other names for this target antigen include MAP11, MCPH25, microtubule associated protein 11, trafficking protein particle complex 14, uncharacterized protein C7orf43, and C7orf43. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species.
