Predicted Molecular Mass:109.5 kDa SDS-PAGE:135-155 kDa, reducing conditions Activity:Measured by its ability to enhance neurite outgrowth of E16-E18 rat embryonic cortical neurons.Immobilized rmContactin-4 (as a 3 µL droplet containing 100 ng) on a nitrocellulose coated microplate is sufficient to significantly enhance neurite outgrowth. Formulation:Lyophilized from a 0.2 µm filtered solution in PBS.See Certificate of Analysis for details. Molecule Information: Contactin-4 Aliases: BIG-2; CNTN4 Entrez Gene IDs: 152330 (Human) Background: Contactin-4 Contactin-4 (CNTN4), also known as BIG-2 (brain-derived immunoglobulin superfamily molecule 2), is an axonal cell adhesion molecule that belongs to the contactin family, a subfamily of the Ig superfamily. Contactin family members are characterized by the presence of six Ig-like domains, four fibronectin type III-like repeats, and a glycosylphosphatidylinositol (GPI)-anchoring domain. Three alternative transcripts of CNTN4, encoding isoforms a, b, and c precursor proteins containing 1026, 282, and 698 amino acid residues, respectively, have been described.
