Preparation and Storage

Background: SLAM/CD150

The type I transmembrane glycoprotein Signaling Lymphocytic Activation Molecule (SLAM), also known as CD150, is the prototypic member of the SLAM subgroup of the CD2 protein family. CD2 family proteins function as adhesion molecules and modulators of the immune response (1). Mouse SLAM consists of a 218 amino acid (aa) extracellular domain (ECD) with two Ig-like domains, a 23 aa transmembrane segment, and a 78 aa cytoplasmic domain with three immunoreceptor tyrosine switch motifs (ITSM) (2). Alternate splicing generates an isoform with a substituted cytoplasmic domain (2). Within the ECD, mouse SLAM shares 58% and 83% aa sequence identity with human and rat SLAM, respectively. It is expressed as a 75 kDa molecule of which approximately 30 kDa is N-linked carbohydrate (2). SLAM is expressed on T cells, B cells, thymocytes, macrophages, dendritic cells, platelets, and hematopoietic stem cells (2‑7). It is upregulated on activated B cells and CD4⁺ and CD8⁺ T cells, although it is downregulated on Th2 polarized cells (2, 3, 8). SLAM interacts homophilically with low affinity, and this interaction induces a Th0/Th1 response characterized by clonal expansion, production of IFN-gamma, and increased cytolytic activity of CD8⁺ T cells (2, 3, 9‑11). SLAM ligation also promotes B cell activation, allergen-induced eosinophil and mast cell activation, and macrophage responsiveness to LPS (4, 8, 12). In humans, SLAM functions as a cellular entry receptor for measles virus (13, 14).
