General description

Contactin-associated protein 1(Caspr) is a single-pass type I membrane protein belonging to the neurexin family and is comprised of one F5/8 type C domain, one fibrinogen C-terminal domain, two EGF-like domains, and four laminin G-like domains. Caspr is well documented for its interaction with contactin, an interaction that is crucial to the transport of Caspr to the plasma membrane, the mylination of glial cells, and the generation of axoglial junctions. Studies also suggest that Caspr may play a regulatory role in the cell surface expression of contactin and its targeting to different axonal domains. Expression of Caspr is largely observed in the brain, mainly in CNS myelinated nerve fibers within paranodal axoglial junctions.
