Myelin basic protein (MBP) is a protein believed [weasel words] to be important in the process of myelination of nerves in the nervous system. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction . [ 5 ]
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. [ 2 ] In humans, point mutations in PLP are the cause of Pelizaeus–Merzbacher disease (PMD), a neurologic disorder of myelin metabolism.
Myelin's best known function is to increase the rate at which information, encoded as electrical charges, passes along the axon's length. Myelin achieves this by eliciting saltatory conduction. [1] Saltatory conduction refers to the fact that electrical impulses 'jump' along the axon, over long myelin sheaths, from one node of Ranvier to the next.
Myelinogenesis is the formation and development of myelin sheaths in the nervous system, typically initiated in late prenatal neurodevelopment and continuing throughout postnatal development. [1] Myelinogenesis continues throughout the lifespan to support learning and memory via neural circuit plasticity as well as remyelination following ...
PMP22/gas-3, called peripheral myelin protein, is located in the myelin sheath. The expression of this protein is associated with a differentiation of Schwann cells, an establishment of tight junction in the Schwamm cell membrane or a compact formation of myelin. It is also present in epithelial cells of lungs and intestine, where interacts ...
Peripheral myelin protein 22 (PMP22), also called Growth arrest-specific protein 3 (GAS-3), is a protein which in humans is encoded by the PMP22 gene.
A nerve tissue protein is a biological molecule related to the function and maintenance of normal nervous tissue. [1] An example would include, for example, the generation of myelin which insulates and protects nerves. These are typically calcium-binding proteins.
The insulation must be proportional to the diameter of the fibre inside. The optimal ratio of axon diameter divided by the total fiber diameter (which includes the myelin) is 0.6.
