Myelin proteolipid protein
Myelin proteolipid protein (PLP or lipophilin) is the major myelin protein from the central nervous system (CNS). It plays an important role in the formation or maintenance of the multilamellar structure of myelin. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the efficiency of axonal impulse conduction.
