Anti-FAM134C antibodies enable researchers to detect and measure the FAM134C antigen in biological samples. This target is a reported synonym of the RETREG3 gene, which encodes reticulophagy regulator family member 3. This protein is known to function in neuronal development, among other biological roles. The human version of FAM134C has a canonical amino acid length of 466 residues and a protein mass of 51.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER of cells. FAM134C is a member of the RETREG protein family.
