Discovery sheds light on protein key to nerve cells’ myelin sheath

Genetic mutations in PMP22 (peripheral myelin protein 22) cause a variety of peripheral neuropathies, underscoring the importance of the protein to a healthy peripheral nervous system. But the precise function of PMP22, a major component of the myelin sheath that surrounds and insulates peripheral nerve cell axons, has been unclear.
