A recently discovered protein called malectin is known to recognize the Glc(2)Man(9)GlcNAc(2) glycan (Schallus T et al, 2008). The exact role of this interaction is not clear but malectin is thought to regulate the availability of this substrate to glucosidase II, or to act as a chaperone to stabilize the unfolded protein.
