Anti-F5F8D antibodies are protein reagents that detect specific antigens. The F5F8D antigen is another term for the human protein lectin, mannose binding 1, encoded by the LMAN1 gene. The protein is known to function in Golgi transport and Golgi organization, among other biological roles. Canonically, it has an amino acid length of 510 residues and a mass of 57.5 kilodaltons. Its subcellular localization is in the ER and Golgi and it is ubiquitously expressed across many tissue types.
