Anti-FAM134A antibodies are used in antigen-specific immunodetection in biological samples. The target FAM134A is a known alias name of the protein reticulophagy regulator family member 2, encoded by the RETREG2 gene in humans. This 543-amino acid residue protein is a member of the RETREG protein family. It is localized to the ER of the cell. It is reported to be expressed in many tissues, such as the cerebral cortex and testis.
