Anti-VPS54 subunit of GARP complex antibodies are used for the immunodetection of the protein encoded by the VPS54 gene. In humans, the canonical protein has a reported length of 977 amino acid residues and a mass of 110.6 kDa. Its subcellular localization is in the Golgi. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of the VPS54 protein family, it is known to act as component of the GARP complex that is involved in retrograde transport from early and late endosomes to the trans-Golgi network (TGN). Other names for this target antigen include PPP1R164, SLP-8p, VPS54L, WR, hVps54L, and HCC8. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
