WebThe Lutheran inhibitor blood group phenotype (In (Lu)) is characterized phenotypically by the apparent absence of the Lu antigen ( BCAM ) on red blood cells during serologic tests, i.e., Lu (a-b-). Since it is inherited as an autosomal dominant trait, it was initially postulated to result from an inhibitor of the Lu antigen. WebRefSeq Summary (NM_001013257): This gene encodes Lutheran blood group glycoprotein, a member of the immunoglobulin superfamily and a receptor for the extracellular matrix protein, laminin. The protein contains five extracellular immunoglobulin domains, a single transmembrane domain, and a short C-terminal cytoplasmic tail.
