Basal cell adhesion molecule, also known as Lutheran antigen, is a plasma membrane glycoprotein that in humans is encoded by the BCAM gene.[5] BCAM has also recently been designated CD239 (cluster of differentiation 239).


Lutheran blood group glycoprotein is a member of the immunoglobulin superfamily and a receptor for the extracellular matrix protein, laminin. The protein contains five, N-terminus, extracellular immunoglobulin domains, a single transmembrane domain, and a short, C-terminal cytoplasmic tail. This protein may play a role in epithelial cell cancer and in vaso-occlusion of red blood cells in sickle cell disease. Two transcript variants encoding different isoforms have been found for this gene.[5]


BCAM has been shown to interact with Laminin, alpha 5.[6][7]
