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). Interacts with PXL1. Highly expressed in the cambial zone of the stem vasculature (at protein level). Expressed in roots, rosettes leaves, stems, cauline leaves, flowers and siliques. By cold stress (PubMed:15165189). Phosphorylated in vivo (Ref.8). Phosphorylated in vitro by PXL1 (PubMed:25602612). Belongs to the KS-type dehydrin family.
