Background: Contactin-3

Contactin-3, also known as BIG-1, CNTN3 and PANG, is a 150 kDa member of the TAG/F3 subgroup of Contactin neuronal adhesion proteins (1, 2). Mature human Contactin-3 consists of six immunoglobulin-like domains, a flexible linker region, four fibronectin type III domains, and a GPI anchor (3, 4). Human Contactin-3 shares 92% aa sequence identity with mouse and rat Contactin-3. Contactin-3 is primarily expressed in the brain in discrete regions including the frontal lobe, occipital lobe, cerebellum, amygdala, and hippocampus (5, 6). Alternative splicing in rat may generate a soluble isoform (4). Mouse plasmacytoma cell lines produce multiple transcripts of Contactin-3 due to the presence of IAP proviruses (3). Immobilized Contactin-3 promotes neurite outgrowth from rat hippocampal neurons (4).
