Scientific Data
Detection of Human, Mouse, and Rat Contactin‑2/TAG1 by Western Blot. Western blot shows lysates of human cerebellum tissue, mouse brain tissue, and rat brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat Contactin-2/TAG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4439) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Contactin-2/TAG1 at approximately 135 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Contactin‑2/TAG1 in Mouse Embryo. Contactin-2/TAG1 was detected in immersion fixed frozen sections of mouse embryo (E13) using Goat Anti-Human/Mouse/Rat Contactin-2/TAG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4439) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to muscle cells in proximity to ribs. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: Contactin-2/TAG1
Contactin-2 (CNTN2), also called TAG1 (transient axonal glycoprotein), TAX1 (transiently-expressed axonal glycoprotein), or axonin-1, is a 135 kDa glycosyl-phosphatidylinositol (GPI)- anchored cell adhesion molecule that belongs to the contactin subfamily within the immunoglobulin (Ig) protein superfamily (1-3). Mouse Contactin-2 cDNA encodes a 30 amino acid (aa) signal peptide, a 984 aa mature secreted protein with 6 Ig-like domains followed by 4 fibronectin type III-like repeats, and a 26 aa C-terminal GPI anchor pro-sequence. GPI-specific phospholipase activity can release soluble, active Contactin-2 from the membrane (2). Mature mouse Contactin-2 shares approximately 93%, 97%, and 77% aa sequence identity with human, rat, and chicken Contactin-2, respectively. During development, Contactin-2 is expressed by a subset of neuronal populations in the central nervous system (CNS) and peripheral nervous system (PNS), particularly during initial phases of axon outgrowth (3-5). Both the 135 kDa form and a 90 kDa form are also upregulated in response to CNS injury in the adult (6). Data support a role for Contactin-2 in axon pathfinding, neurite outgrowth and adhesion, especially in the CNS (3-6). In mature myelinated fibers, Contactin-2 is expressed by oligodendrocytes and Schwann cells, which are myelinating glial cells of the CNS and PNS, respectively (7, 8). It is enriched in the juxtaparanodal regions, where it recruits contactin-associated protein 2 (caspr2), a transmembrane neurexin involved in cell adhesion and intercellular communication (7-10). The axonal Contactin-2 interacts in cis with caspr2 and in trans with another Contactin-2 on the glial membrane (8). This ternary complex is required for the accumulation and organization of K+ channels in the juxtaparanodes (9).
