CD157 is an ectoenzyme member of the ADP-ribosyl cyclase family, also known as ADP-ribosyl cyclase 2, BST-1 (bone marrow stromal cell antigen 1), BP-3 antigen. It has a molecular weight between 40 - 46 kD and is a GPI-linked cell membrane glycoprotein which is expressed as a homodimer. CD157 is expressed by macrophages, neutrophils, bone marrow stromal cells, endothelial cells, follicular dendritic cells, and T and B cell progenitors prior to the rearrangement of the antigen receptors. Besides the ectoenzyme activity, it also plays a role in neutrophil migration and adhesion.

Antigen Details

Member of the ADP-ribosyl cyclase family, ectoenzyme, 40-46 kD, glycosyl-phosphatidylinositol (GPI)- anchored membrane protein, present on the cell surface as a homodimer

Expressed by endothelial cells, follicular dendritic cells, cells from the myeloid lineage, and T and B cell precursors prior to the rearrangement of the antigen receptor. Expressed in many cell types from different tissues like the bone marrow, spleen, thymus, lung, kidney and heart.

Synthesizes cyclic ADP-ribose (cADPR), a second messenger that elicits calcium release from intracellular stores.
