May play a role in action potential conduction in myelinated cells through the organization of molecular complexes at nodes of Ranvier and axon initial segments . May also play a role in axon outgrowth and guidance (By similarity).
Subcellular locations: Cell projection, Axon, Cytoplasm
Localizes to the axon initial segments (AIS) and nodes of Ranvier of neurons and is absent from dendrites.
Highly expressed in brain and to a lower extent in heart and kidney.
