Anti-FAM20A golgi associated secretory pathway pseudokinase antibodies are used for the immunodetection of the protein encoded by the FAM20A gene. In humans, the canonical protein has a reported length of 541 amino acid residues and a mass of 61.4 kDa. Its subcellular localization is in the ER, Golgi, and is secreted. It is reported to be highly expressed in the lung and liver. A member of the FAM20 protein family, it is a reported pseudokinase that acts as an allosteric activator of the Golgi serine/threonine protein kinase FAM20C and is involved in biomineralization of teeth. Post-translational modifications have been described, including N-glycosylation. The gene encoding this protein is implicated in Amelogenesis imperfecta 1G. Other names for this target antigen include AIGFS, FP2747, pseudokinase FAM20A, family with sequence similarity 20, member A, protein FAM20A, and AI1G. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species.
