Function
Intrinsically disordered and metal-binding protein. Binds to the divalent cations cobalt, nickel, copper and zinc, but not to magnesium, calcium, manganese or cadmium (Ref.8). Binding to metal ions decreases disordered state, decreases susceptibility to trypsin and promotes self-association. Can reduce the formation of reactive oxygen species (ROS) in a copper-ascorbate in vitro system (PubMed:23382551).
