Description

QA20A43 recognizes human CD239, also known as Lutheran antigen or Basal Cell Adhesion Molecule (B-CAM). Human CD239 is a type I transmembrane glycoprotein that is encoded by B-CAM which belongs to the Ig gene superfamily. Full-length BCAM (CD239) is comprised of an extracellular region with two N-terminal V-type Ig-like domains followed by three C2-type Ig-like domains, a transmembrane region, and cytoplasmic domain of 59 amino acid residues. CD239 is expressed on erythrocytes in the peripheral blood and on the basal layer of vascular endothelial cells or some epithelial cells.
