Research at Queen's University have sequenced and synthesised the anti-freeze-like protein that allows snow fleas to operate in sub-zero environments, and found its sequence to be glycine-rich, and unlike any previously known protein. There are hopes that similar proteins may be useful for storing transplant organs and for producing better ice cream. By preventing the formation of ice crystals in tissues, organs could be stored at lower temperatures, increasing their lifespan outside a living body. Unlike proteins with similar functions in other species, the protein found in snow fleas breaks down easily at higher temperatures.References:
