- Presumed formation from a precursor rich in glutamine and aspartic acid. In contrast to the effective MBP, the precursor is not toxic. Intracellular can be transported safely through the endoplasmic reticulum. Maturation to the effective MBP in the granules of mast cells.
- MBP is toxic to helminths and is therefore involved in immune reactions against parasites (primary task). Toxicity is also directed against epithelia of the respiratory tract (nasal mucosa, bronchi). It also has the ability to stimulate mast cells to release histamine.
