BST1, also known as ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2, is a glycosylphosphatidyl inositol (GPI) anchored membrane protein that belongs to the CD38 family. It was originally identified as a bone marrow stromal cell molecule. This protein is an ectoenzyme sharing several characteristics with ADP-ribosyl cyclase CD38. Along with CD38, it exhibits both DP-ribosyl cyclase and cyclinc ADP ribose hydrolase activities. It may play a role in rheumatoid arthritis (RA) due to its enhanced expression in RA-derived bone marrow stromal cell lines. Also, it is expressed by cells of the myeloid lineage and could act as a receptor with signal transduction capability.
