Conservation and restoration of fur objects made from keratin, which is also the protein that makes up skin, feathers, nails, hooves, claws, and horns. "The way I think a lot of people understand fur versus hair is in the density of follicles," says Ross McPhee, Curator of the Department of Mammalogy at the American Museum of Natural History. "So for fur-bearing animals—which were converted into coats and so-forth—people always wanted it to be something that was very dense, so there’s the idea therefore that fur is dense, and it certainly is in [the] kinds of fur-bearers that we use for this purpose. Whereas hair is not
Major basic protein MBP does not bind either calcium or any of the other carbohydrates that this family recognize. Instead, MBP recognises heparan sulfate proteoglycans. Two crystallographic structures of MBP have been determined. Major basic protein has been shown to interact with Pregnancy-associated plasma protein A. arylsulfatase Major basic protein Eosinophil Major basic protein, often shortened to Major basic protein (MBP) (also called Proteoglycan 2(PRG2)) in humans is encoded by the "PRG2" gene. The protein encoded by this gene is the predominant constituent of the crystalline core of the eosinophil granule. High levels of the proform of this protein are also present in
