Anti-family with sequence similarity 187 member A antibodies are used for the immunodetection of the protein encoded by the FAM187A gene. In humans, the canonical protein has a reported length of 413 amino acid residues and a mass of 47.3 kDa. Its subcellular localization is in the membrane. It is a member of the FAM187 protein family. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include Ig-like V-type domain-containing protein FAM187A. Gene orthologs have been identified in the mouse, rat, bovine and chicken species.
