Anti-FAM20C golgi associated secretory pathway kinase antibodies are used for the immunodetection of the protein encoded by the FAM20C gene. In humans, the canonical protein has a reported length of 584 amino acid residues and a mass of 66.2 kDa. Its subcellular localization is in the ER, Golgi, and is secreted. Alternative splicing is reported to yield 2 different isoforms for this protein. It is widely expressed across many tissue types. A member of the FAM20 protein family, it is known to be involved with the differentiation of certain cell types. Post-translational modifications have been described, including N-glycosylation, protein cleavage and phosphorylation. The gene encoding this protein is implicated in Raine syndrome. Other names for this target antigen include Golgi casein kinase, dentin matrix protein 4, family with sequence similarity 20, member C, golgi-enriched fraction casein kinase, and extracellular serine/threonine protein kinase FAM20C. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
