Description
Biochem/physiol Actions
GSK484 is a potent selective reversible inhibitor of protein arginine deiminase PAD4, an enzyme believed to play a role in granulocyte and macrophage development leading to inflammation and immune response, and overexpressed in many tumors. GSK484 has IC₅₀ values of 50 nM without calcium and 250 nM in the presence of 2 mM calcium. GSK484 showed minimal off-target activity tested against 50 other proteins with no activation across HDACs 1–11 even at 100 μM. GSK484 binds at a different site from the amidines, a conformation of the PAD4 active site where part of the site is reordered to form a β-hairpin.
