Myelin basic protein (MBP) is a crucial protein found in the central nervous system, primarily in the myelin sheath that surrounds nerve fibers. This sheath is essential for the proper conduction of electrical impulses along neurons, facilitating efficient communication between different parts of the brain and body. MBP plays a significant role in the formation and maintenance of myelin. It helps stabilize the structure of the myelin sheath and is involved in the process of myelination during the development of the nervous system. Abnormalities in MBP can lead to neurological disorders, including multiple sclerosis.
