Anti-family with sequence similarity 53, member A antibodies are used in antigen-specific immunodetection in biological samples. The target family with sequence similarity 53, member A is a known alias name of the protein family with sequence similarity 53 member A, encoded by the FAM53A gene in humans. This 398-amino acid residue protein is believed to play an important role in neural development; the dorsomedial roof of the third ventricle. It is localized to the nucleus of the cell. It is reported to be expressed in many tissues, such as the cerebral cortex, vagina, and breast.
