A novel role for the non‐catalytic intracellular domain of Neprilysins in muscle physiology

Abstract

These data demonstrate that the physiological significance of Nep4 is not limited to its function as an active peptidase but that the enzyme's intracellular N-terminus is affecting muscle integrity, independent of the protein's enzymatic activity. To our knowledge, this is the first report of an intracellular Nep domain being involved in muscle integrity.
