Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).

Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.

The process in which the structure and material content of mature central nervous system myelin is kept in a functional state.

The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of oligodendrocytes in the central nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.

The process aimed at the progression of an oligodendrocyte over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. An oligodendrocyte is a type of glial cell involved in myelinating the axons in the central nervous system.

The process in which a relatively unspecialized cell acquires the specialized features of an oligodendrocyte. An oligodendrocyte is a type of glial cell involved in myelinating the axons of neurons in the central nervous system.

Any process that activates or increases the frequency, rate or extent of the formation of a myelin sheath around nerve axons.

Any process that activates or increases the frequency, rate or extent of cellular DNA-dependent transcription.

The cellular synthesis of RNA on a template of DNA.
