Specificity: Human CD299, which is an oligomeric type II transmembrane protein with a C-type lectin extracellular domain, the expression of which is restricted to immature DC, macrophages in the lung, and endothelial cells in the liver. It binds ICAM-3 and ICAM-7 to mediate the interaction of DC with T lymphocytes and endothelial cells in the initial stages of immune response and in the migratory behavior of DC. CD299 also binds the gp120 protein of HIV and the E2 envelope protein of HCV, thereby playing a role in viral infection.
CLEC4M is a type II integral membrane protein that is 77% identical to CD209 antigen, a HIV gp120-binding protein. This protein, like CD209, efficiently binds both intercellular adhesion molecule 3 (ICAM3) and HIV-1 gp120, and enhances HIV-1 infection of T cells.Western blots using two different antibodies against two unique regions of this protein target confirm the same apparent molecular weight in our tests.This gene encodes a type II integral membrane protein that is 77% identical to CD209 antigen, a HIV gp120-binding protein. This protein, like CD209, efficiently binds both intercellular adhesion molecule 3 (ICAM3) and HIV-1 gp120, and enhances HIV-1 infection of T cells. This gene is mapped to 19p13.3, in a cluster with the CD209 and CD23/FCER2 genes. Multiple alternatively spliced transcript variants have been found for this gene, but the biological validity of some variants has not been determined.
