This is amino acids 86 to 100 fragment of class II-associated invariant chain peptide called CLIP. The major histocompatibility complex class II molecule displays peptide fragments of foreign proteins to trigger a defensive reaction from the immune system. Before insertion of the foreign peptides into the binding groove, a place-holding peptide CLIP is removed. This is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.

GCN2-IN-6 is a potent and orally available GCN2 inhibitor confirmed by in-house enzymatic (IC50: 1.8 nM) and cellular assays (IC50: 9.3 nM).?
