Anti-golgin A6 family like 9 antibodies are used for the immunodetection of the protein encoded by the GOLGA6L9 gene. In humans, the canonical protein has a reported length of 432 amino acid residues and a mass of 49.2 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the GOLGA6 protein family. Other names for this target antigen include golgi autoantigen, golgin subfamily a, 6-like 9, golgin A6 family-like 20, putative golgin subfamily A member 6-like protein 20, and golgin subfamily A member 6-like protein 9.
