Target Information
LAG-3 is a 70-kDa surface glycoprotein belonging to the immunoglobulin superfamily with homology to CD4.
It binds to MHC class II with higher affinity than CD4 and is involved in the negative regulation of T cell activation and homeostatic proliferation.
Surface expression of LAG-3 has been reported on activated T cells (including regulatory T cells) and NK cells.
CD8+ T cells generally express higher levels of LAG-3 than CD4+ T cells.
Coexpression of LAG-3 and CD49b has been proposed as a marker for Type 1 regulatory T cells (Tr1 cells) in both humans and mice.
