Anti-TMEM57 antibodies enable researchers to detect and measure the TMEM57 antigen in biological samples. This target is a reported synonym of the MACO1 gene, which encodes macoilin 1. This protein is known to function in brain development and chemotaxis, among other biological roles. The human version of TMEM57 has a canonical amino acid length of 664 residues and a protein mass of 76.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and ER of cells. Other names for this target antigen include MACOILIN and transmembrane protein 57.
