Neurofascin 155 (NF155) is a type I transmembrane glycoprotein that belongs to the L1CAM family of cell adhesion proteins (1, 2). The rat NF155 cDNA encodes a 1240 amino acid (aa) precursor that contains a 24 aa signal sequence, a 1086 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 109 aa cytoplasmic domain. The ECD consists of six Ig-like domains and four fibronectin type III repeats, the second of which has an RGD motif. A splice variant of Neurofascin, NF186, lacks the RGD-containing fibronectin type III domain but instead has a mucin-like domain and an additional non-RGD fibronectin type III domain (3). Within shared regions of the ECD, rat NF155 shares 45% and 39% aa sequence identity with rat Nr-CAM and L1CAM, respectively, and 98% aa sequence identity with human and mouse NF155. NF155 is transiently expressed by oligodendrocytes at the onset of axon myelination, whereas NF186 is neuronally expressed in nodes of Ranvier (4‑6). Clustering of NF155 in paranodal oligodengroglia lipid raft domains is stabilized by dimerization of its cytoplasmic domains and association with intracellular ankyrin (6‑9). NF155 interacts with axonal contactin and plays a role in node of Ranvier formation and the establishment of saltatory conduction (5, 9‑12). The ECD of NF155 is cleaved from oligodengroglia membranes by metalloproteases, a process which is required for NF155 transport from the glial cell body to the axoglial junction (13). In addition to distinct expression patterns, Neurofascin isoforms have different functional properties. NF155 promotes neuronal adhesion and neurite outgrowth, whereas NF186 inhibits neuronal adhesion (4, 7, 13).

FAQs for Neurofascin Antibody (AF3235). (Showing 1 - 1 of 1 FAQs).

  1. Does the neurofascin antibody #AF3235 detect both 155 and 186 isoforms?
    • The immunogen for this antibody is "Mouse myeloma cell line NS0-derived recombinant rat Neurofascin Ile25 - Ala1031". It means that any protein target has the the partial or full-length region that is included in Ile25 - Ala1031 will be recognized because it is a polyclonal antibody. Then, I checked the rat sequence posting on UniProt (, it says that rat has three Neurofascin isoforms: 1 to 3. Isoform has 1,240 a.a. with a mass of 138,004 (Da), whereas both isoforms 2 and 3 are known as "NF155, 155 kDa isoforms" According above information, the isoforms 2 and 3 should also be recognized by the antibody, AF3235, because the missing and sequence-substituted regions are not excluded out of "Ile25 - Ala1031"; and there are still a lot of epitopes left on the protein species for binding. Unfortunately, I did not locate any information on isoform 186 (assuming this isoform has ~186 kDa) in rat, human Uniprot, or mouse Uniprot databases. If you have the a.a. sequence for the isoform, you could analyze the structure and determine whether AF3235 can recognize it.
