General annotation (Comments)
| Function | Cell adhesion, ankyrin-binding protein which may be involved in neurite extension, axonal guidance, synaptogenesis, myelination and neuron-glial cell interactions. Isoform 2/isoform 3 may be responsible for mediating and signaling axon-glial interaction during the early stages of myelination. Ref.3 Ref.4 Ref.6 |
| Subunit structure | Horseshoe-shaped homodimer By similarity. Probable constituent of a neurofascin/NRCAM/ankyrin G complex. Associates with the sodium channel beta-1 (SCN1B) and beta-3 (SCN3B) subunits. Associates to subunit beta-1 in developing axons as early as postanatal day 5, during the period that nodes of Ranvier are forming. Isoform 2/isoform 3 is likely to interact with axonal proteins in close association with CNTNAP1. Interacts with GLDN/gliomedin. Ref.2 Ref.5 Ref.6 |
| Subcellular location | Cell membrane; Single-pass type I membrane protein. Note: Isoform 1 colocalizes with ankyrin G at the nodes of Ranvier. Isoform 2/ isoform 3 is a glial component of the paranodal axo-glial junction. |
| Tissue specificity | Isoform 1 is expressed at Nodes of Ranvier while isoform 2/isoform 3 is expressed in unmyelinated axons. Ref.4 |
| Developmental stage | Strongly but transiently up-regulated in oligodendrocytes at the onset of myelinogenesis. Once these last have engaged their target exons, expression declines precipitously. |
| Domain | Homophilic adhesion is primarily mediated by the interaction of the second Ig-like domains By similarity. |
| Post-translational modification | Isoform 2/isoform 3 is phosphorylated at P12. Dephosphorylation is required for ankyrin binding. Ref.4 |
| Sequence similarities | Belongs to the immunoglobulin superfamily. L1/neurofascin/NgCAM family. Contains 4 fibronectin type-III domains. Contains 6 Ig-like C2-type (immunoglobulin-like) domains. |
