Human Signaling Lymphocytic Activation Molecule Family Member 1 / CD150 (SLAMF1) Protein

Background

SLAMF1, also known as CD150, is a membrane glycoprotein and member of the signaling lymphocytic activation molecule (SLAM) family, which plays a critical role in modulating immune responses. It is encoded by the SLAMF1 gene and is primarily expressed on the surface of several immune cells, such as T cells, B cells, macrophages, and dendritic cells. SLAMF1 functions as a self-ligand, allowing it to engage in homophilic interactions that are essential for intercellular communication in immune responses. It influences a variety of immune processes, including cell activation, proliferation, cytokine production, and cytotoxic functions. This molecule plays a significant role in adaptive immunity by regulating immune cell interactions, positioning it as a critical factor in the immune response to pathogens and in autoimmune conditions.
