Drug targets a biomolecule that can directly bind to drugs and then react. Generally, the target refers to a protein, which is related to the cause of disease. The focus of the target began with focusing on tumors, and then began to spread to various fields .CD150/SLAM protein is a common target in medicine.

CD150 is also known as the signaling lymphocyte-activating molecule, SLAM. CD150 is also the most common receptor of the genus measles virus, which is a membrane glycoprotein expressed on host immune cells and has immune specificity to the genus measles virus. CD150 is a single-stranded phosphoglycoprotein, which includes two already highly glycosylated immunoglobulin superfamily domains, a member of the CD2 family, and like other members, CD150 has two extracellular domains: the N-terminal membrane-distal type V set and the juxtamembrane C2 type set. CD150 is also a molecular protein that can bind itself to produce costimulators. It activates T cells, B lymphocytes, dendritic cells, and macrophages and rapidly these cells to differentiate. CD150 is also a molecular protein that can bind itself to produce costimulators. It activates T cells, B lymphocytes, dendritic cells, and macrophages and rapidly these cells to differentiate. CD150 As a viral receptor is a good explanation of why the host has immune suppression and other phenomena after the virus infection.
