PHILADELPHIA – Cells have their own version of the cut-and-paste editing function called splicing. Researchers at the University of Pennsylvania School of Medicine have documented a novel form of splicing in the cytoplasm of a nerve cell, which dictates a special form of a potassium channel protein in the outer membrane. The channel protein is found in the dendrites of hippocampus cells -- the seat of memory, learning, and spatial navigation -- and is involved in coordinating the electrical firing of nerve cells.
