FGL1 Fc Chimera, Human

FGL1 (Fibrinogen-like protein 1), also known as hepatocyte-derived fibrinogen-related protein 1 (HFREP-1), HP-041, hepassocin (HPS), and liver fibrinogen-related protein 1 (LFIRE-1), is a liver-specific secreted protein belonging to the fibrinogen superfamily whose members share a fibrinogen domain at their C-termini. FGL1 is an immune suppressive molecule that inhibits the activation of antigen-specific T cells by acting as a major ligand of LAG3, and binds LAG3 independently of MHC class II.
