Target Information
LAG-3 is a 70-kDa surface glycoprotein belonging to the Ig 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 is reported on activated T cells (including regulatory T cells) and NK cells.
CD8+ T cells usually express LAG-3 at higher levels than CD4+ T cells.
Coexpression of LAG-3 and CD49b has been proposed to identify human and mouse Type 1 regulatory T cells (Tr1 cells).
