Synonyms | CASPR, NRXN4 |
Function | Required, with CNTNAP2, for radial and longitudinal organization of myelinated axons. Plays a role in the formation of functional distinct domains critical for saltatory conduction of nerve impulses in myelinated nerve fibers. Demarcates the paranodal region of the axo-glial junction. In association with contactin involved in the signaling between axons and myelinating glial cells. |
Cellular Location | Membrane; Single-pass type I membrane protein. Cell junction, paranodal septate junction {ECO:0000250|UniProtKB:O54991} |
Tissue Location | Predominantly expressed in brain. Weak expression detected in ovary, pancreas, colon, lung, heart, intestine and testis |
