  • Abstract
  • Look Inside

The nervous system is composed of mainly two types of cells, neurons and glial cells. Oligodendrocyte is one of the glial cells, and is responsible for forming myelin which is an important structure to facilitate conduction of nerve impulses. Myelin proteins are specifically expressed in the oligodendrocyte, therefore these proteins are good materials to study gene expression in the nervous system. The two alleic mutants shiverer and myelin deficient are characterized by abnormal expression of the myelin basic protein (MBP) gene. MBP makes up about 30% of total myelin protein and is thought to be located at the major dense line of myelin, which is formed by the fusion of the cytoplasmic surfaces of the oligodendrocyte plasma membrane during myelination.
