OnCo

FGL1 is a liver protein that some tumours secrete; it binds LAG-3 on T cells and switches them off, separately from the MHC class II route. It explains part of how LAG-3 blockade works. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
