This antibody reacts with CD58 (LFA-3), a 40-70 kDa extracellular membrane glycoprotein distributed over many tissues, leukocytes, erythrocytes, endothelial cells, epithelial cells and fibroblasts.
CD58 is a member of the immunoglobulin superfamily and exists both as a transmembrane protein and a GPI-linked extracellular protein, with cells capable of expressing both forms concurrently. Additionally, soluble CD58 has been detected in serum, urine, and synovial fluid, particularly in patients with rheumatoid arthritis. CD58 is widely expressed on non-hematopoietic and most hematopoietic cells. CD58 serves as a ligand for the CD2 protein on T lymphocytes, playing a crucial role in adhesion and activation of T cells. The interaction between CD58 and CD2 initiates a signaling pathway that includes phosphorylation and leads to cytokine release. This interaction is important for T cell activation, cytokine production, cytotoxicity, and adhesion to various cell types. The protein is localized to the plasma membrane, and alternatively spliced transcript variants have been described, indicating diverse functional roles. CD58's involvement in immune responses highlights its significance in both normal physiological processes and disease states.
