Anti-SMP1 antibodies enable researchers to detect and measure the SMP1 antigen in biological samples. This target is a reported synonym of the TMEM50A gene, which encodes transmembrane protein 50A. The human version of SMP1 has a canonical amino acid length of 157 residues and a protein mass of 17.4 kilodaltons. It is reported to be localized in the membrane of cells. SMP1 is a member of the UPF0220 protein family.
