May play a role in the formation of functional distinct domains critical for saltatory conduction of nerve impulses in myelinated nerve fibers. Seems to demarcate the juxtaparanodal region of the axo-glial junction. Associates with KCNA2. Predominantly expressed in nervous system. Belongs to the neurexin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Membrane protein, integral; Motility/polarity/chemotaxis
Chromosomal Location of Human Ortholog: 7q35-q36.1
