CD299, as known as DC-SIGNR and CLEC4M, is a type II integral membrane protein that is 77% amino acid identical to CD209/DC-SIGN, an HIV gp120-binding protein. This protein is probable pathogen-recognition receptor involved in peripheral immune surveillance in liver. It may mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. CD299 is a receptor for ICAM3, binding to mannose-like carbohydrates. It also recognizes a wide range of evolutionarily divergent pathogens with a large impact on public health, including tuberculosis mycobacteria, and viruses including Ebola, hepatitis C, HIV-1, influenza A, West Nile virus and the SARS-CoV acute respiratory syndrome coronavirus. Recombinant human CD299, fused to hIgG-His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
