Background: Contactin-1

Contactin-1 (CNTN1), also known as F3 and F11, is an approximately 135 kDa GPI-anchored member of the Contactin family of neuronal adhesion glycoproteins (1). Mature mouse Contactin-1 contains 6 Ig-like domains and 4 fibronectin type III-like domains, and it shares 96% and 100% amino acid (aa) sequence identity with human and rat Contactin-1, respectively (2, 3). Alternative splicing generates an isoform with an 11 aa deletion N-terminal to the first Ig-like domain and another isoform that is substituted and truncated following the sixth Ig-like domain. In humans, Contactin-1 is critical in the development of the central nervous system, and a soluble form of Contactin-1 is released into the cerebrospinal fluid (4). Contactin-1 is expressed on neurons and their precursors at sites of glial cell contact with neuronal processes (5-7). Within paranodal regions of the axon, Contactin-1 associates in cis with the transmembrane protein Caspr (7). It binds in trans to other neuronal adhesion proteins (e.g. NrCAM, Neurofascin, Tenascin R), the phosphatase PTPRZ, and the chondroitin sulfate CS-E (8-13). It also binds and activates both Notch-1 and Notch-2 (14). In cancer, Contactin-1 is up-regulated by VEGF-C and is required for VEGF R3/Flt-4 induced tumor cell invasion and metastasis (15). In humans, mutations in CNTN1 cause a familial form of lethal congenital myopathy (16).
