Autoproteolysis
Definition
A biochemical process of spontaneous and autonomous cleavage, degradation, or enzymatic digestion of proteins within a cell or organic tissue, executed by the organism's own proteolytic enzymes (proteases, peptidases). This endogenous structural phenomenon occurs in a controlled manner during autophagy and cellular turnover, but can be triggered destructively and uncontrollably in pathological states of ischemia, acute inflammation, or immediately following cell death (post-mortem necrosis).
