Rat Contactin-1, CNTN1 ELI

Contactins mediate cell surface interactions during nervous system development.

Involved in the formation of paranodal axo-glial junctions in myelinated peripheral nerves and in the signaling between axons and myelinating glial cells via its association with CNTNAP1.

Participates in oligodendrocytes generation by acting as a ligand of NOTCH1.

Its association with NOTCH1 promotes NOTCH1 activation through the released notch intracellular domain (NICD) and subsequent translocation to the nucleus.

Interaction with TNR induces a repulsion of neurons and an inhibition of neurite outgrowth.
