Cell adhesion and neurite outgrowth are promoted by neurofascin NF155 and inhibited by NF186.

Neurofascin (NF) is a neural cell adhesion molecule in the L1-family containing six Ig domains and multiple fibronectin type III (FnIII) repeats in its extracellular region. NF has many splicing variants and two of these are exemplars that have different cellular patterns of expression during development. NF186, which is expressed on neurons, contains an unusual mucin-like region and NF155, which is expressed on glia, contains a unique FnIII repeat with an RGD motif. Analysis of Fc fusion proteins representing different extracellular regions of NF indicate that NF186 inhibits cell adhesion and neurite outgrowth, and the inhibition is associated with the region containing the mucin-like domain. NF155 promotes neural cell adhesion and neurite outgrowth, and the RGD motif in its third FnIII repeat is critical for cell spreading and neurite outgrowth. The results suggest that different splicing variants of NF expressed on neurons and glia play distinct roles during neural development.[1]
