SLAMF1 (Signaling Lymphocyte Activation Molecule Family member 1), also known as CD150. is a transmembrane glycoprotein belonging to the immunoglobulin (Ig) superfamily. It functions as a self-ligand receptor and plays a critical role in modulating immune cell interactions, particularly in T cells, B cells, dendritic cells, and macrophages. SLAMF1 regulates immune responses by facilitating cell-cell communication and activating downstream signaling pathways, such as those involving SAP (SLAM-associated protein) adaptors. Its extracellular region contains two Ig-like domains (V and C2-type), while the cytoplasmic tail features conserved tyrosine-based signaling motifs.
Recombinant SLAMF1 protein is engineered in vitro to study its structural and functional properties, often by expressing its extracellular domain in mammalian or bacterial systems. This protein is purified for use in binding assays, structural studies (e.g., crystallography), or functional experiments to investigate ligand interactions and signaling mechanisms. Researchers utilize recombinant SLAMF1 to explore its role in autoimmune diseases, infections (e.g., measles virus entry via SLAMF1 interaction), and hematological malignancies, where dysregulated SLAMF1 signaling is implicated. Notably, mutations in SLAMF1 are linked to X-linked lymphoproliferative disease type 1 (XLP1), highlighting its importance in immune regulation. The recombinant form also serves as a tool for developing therapeutic antibodies or inhibitors targeting SLAMF1-mediated pathways in conditions like lupus or lymphoma. Its applications extend to vaccine research, given its role as a viral receptor, and immunotherapy design aimed at modulating immune checkpoint-like functions.
