Other investigations have detailed how extracellular signaling proteins and enzymes—ranging from ADP‐ribosyltransferases and matrix metalloproteinase isoforms to regulators of calcineurin/NFAT signaling and myelin differentiation factors—contribute to diverse physiological processes including heme detoxification, immune regulation, and tissue repair.
