Anti-Beta-GALACTOSIDASE antibodies are protein reagents that detect specific antigens. The Beta-GALACTOSIDASE antigen is another term for the human protein galactosidase beta 1, encoded by the GLB1 gene. The protein is known to function in carbohydrate metabolism and homeostasis and the metabolism of lipids, among other biological roles. Canonically, it has an amino acid length of 677 residues and a mass of 76.1 kilodaltons. Its subcellular localization is in the lysosomes and cytoplasm and it is notably expressed in the placenta. The Beta-GALACTOSIDASE protein is a member of the Glycosyl hydrolase 35 protein family. Other alias names for Beta-GALACTOSIDASE include EBP, ELNR1, and MPS4B.
