Signaling Lymphocytic Activation Molecule Family Member 1

**Definition:** A 70-kDa SLAM family receptor that consists of an extracellular IMMUNOGLOBULIN-LIKE DOMAIN and an IMMUNOGLOBULIN C2-SET DOMAIN. It is expressed primarily by THYMOCYTES and activated T-LYMPHOCYTES, as well as by MACROPHAGES and DENDRITIC CELLS. It binds SLAMF1 receptors on other cells to mediate T-cell maturation and proliferation. It is also a receptor for the MEASLES VIRUS.
