Anti-FAM159B antibodies enable researchers to detect and measure the FAM159B antigen in biological samples. This target is a reported synonym of the SHISAL2B gene, which encodes shisa like 2B. The human version of FAM159B has a canonical amino acid length of 160 residues and a protein mass of 17.7 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the pancreas. FAM159B is a member of the Shisa protein family.
