Anti-trafficking protein particle complex subunit 2L antibodies are used for the immunodetection of the protein encoded by the TRAPPC2L gene. In humans, the canonical protein has a reported length of 140 amino acid residues and a mass of 16.1 kDa. Its subcellular localization is in the ER, Golgi, and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in the testis, liver, bladder, lung, spleen and brain, several cell lines and primary chondrocytes cell line. A member of the TRAPP small subunits protein family, it is reported to play a role in vesicular transport from endoplasmic reticulum to Golgi. The gene encoding this protein is implicated in Encephalopathy. Other names for this target antigen include PERRB, trafficking protein particle complex subunit 2-like protein, hematopoietic stem/progenitor cells 176, trafficking protein particle complex 2 like, and HSPC176. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
