Biolegend, 140203, PE anti-mouse CD157 (BST-1) Antibody, 25μg

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.

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