Anti-FAM171A1 antibodies are used in the immunodetection of the protein family with sequence similarity 171 member A1. In humans, the canonical protein has a reported length of 890 amino acid residues and a mass of 97.9 kDa. Its subcellular localization is in the cell membrane. It is found to be expressed in the heart, brain, liver, skeletal muscle, kidney and pancreas. A member of the FAM171 protein family, FAM171A1 is reported to be involved in regulation of the cytoskeletal dynamics, plays a role in actin stress fiber formation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include protein FAM171A1 and astroprincin. FAM171A1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of FAM171A1 antibodies have been mentioned in research publications and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
