• Sugary secrets of a cancer-related protein

  17-09-2017 18:03
  The proteins in human cells are extensively decorated with different types of sugars, a phenomenon called glycosylation. These modifications greatly increase the diversity of protein structure and function, affecting how proteins fold, how they behave, and where they go in cells. New research demonstrates that a rare type of glycosylation profoundly affects the function of a protein important for human development and cancer progression.
