Mutated Brush Border (IMAGE) Cell Press Caption These are ccanning electron micrographs of cells lacking the scaffolding protein ANKS4B. ANKS4B plays a critical role in promoting adhesion between adjacent microvilli. Loss of intermicrovillar adhesion results in dishevelled brush borders, characterized by loosely packed microvilli of variable length. Credit Dr. Scott Crawley, Tyska Laboratory, Vanderbilt.
