Anti-FAM159A antibodies enable researchers to detect and measure the FAM159A antigen in biological samples. This target is a reported synonym of the SHISAL2A gene, which encodes shisa like 2A. The human version of FAM159A has a canonical amino acid length of 190 residues and a protein mass of 20.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. FAM159A is a member of the Shisa protein family.
