Biological function summary
This protein acts as an adhesion molecule that contributes to the myelination process. It exists as part of a molecular complex that interacts with other oligodendrocyte and Schwann cell proteins. This interaction is important for nerve regeneration and the expansion of the myelin sheath during development and repair. MAG also assists in signaling between axons and glial cells improving cellular communication and myelin integrity.
Pathways
MAG significantly impacts pathways such as the Nogo receptor which is associated with inhibiting axonal growth and regeneration. MAG interacts with the NOGO protein and other members of the Nogo receptor signaling pathway where it functions to regulate neuronal growth and regeneration. Furthermore MAG's interplay with NOGO receptor components contributes to limiting excessive sprouting of axons balancing growth and stability of the nervous system.

General info
Function
Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2 (By similarity). Not required for initial myelination, but seems to play a role in the maintenance of normal axon myelination. Protects motoneurons against apoptosis, also after injury; protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2. Required to prevent degeneration of myelinated axons in adults; this probably depends on binding to gangliosides on the axon cell membrane (By similarity). Negative regulator of neurite outgrowth; in dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides. In cerebellar granule cells the inhibition is mediated primarily via binding to neuronal gangliosides. In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides. Inhibits axon longitudinal growth (By similarity). Inhibits axon outgrowth by binding to RTN4R (By similarity). Preferentially binds to alpha-2,3-linked sialic acid. Binds ganglioside Gt1b (By similarity).
