Background: OCIL/CLEC2d

C-type lectin domain family 2 member D (CLEC2D), also known as lectin-like NK cell receptor,as lectin-like transcript 1 (LLT-1) and osteoclast inhibitory lectin (OCIL), is a member of the C-type lectin like (CTL) superfamily of natural killer cell receptors (1, 2). Human OCIL/CLEC2D is highly glycosylated and consists of a cytoplasmic domain, a type II transmembrane domain, a stalk region and a C-type lectin-like (CTL) in the extracellular domain (ECD). Within the ECD, mature human OCIL/CLEC2D shares 45% and 43% amino acid sequence identity with mouse and rat OCIL/CLEC2D, respectively. At least six different isoforms of OCIL/CLEC2D, resulting from alternatively spicing, have been reported (1, 2). OCIL/ CLEC2D plays a role in immunotherapy, inflammation and tissue injury and is expressed mainly on activated lymphocytes (NK cells, T cells, B cells) and antigen presenting cells (1-6).OCIL/CLEC2D forms a disulfide linked homodimer that acts as the only ligand for NKRP1A (CD161) and inhibits NK cell-mediated cytotoxicity and IFN-gamma secretion (1,6,7). OCIL/CLEC2D preferentially binds high molecular weight sulfated glycosaminoglycans and blocks osteoclast differentiation (1, 4).
