Human/Mouse/Rat Teneurin‑2 Alexa Fluor™ Plus 647‑conjugated Antibody

Teneurin-2 (also Ten-2/Ten-m2, tenascin-M2, and Ten-m/Odz2) is a 250-330 kDa member of the tenascin family, teneurin subfamily of transmembrane (TM) molecules. It is a covalently-linked homodimer that is expressed in both embryonic and adult neurons, among which are cerebellar Purkinje cells, pyramidal neurons of the hippocampus, and neurons of layers II and VI of the cerebral cortex. Teneurin-2 appears to promote neurite outgrowth and mediate cell-to-cell adhesion via homophilic interactions. Human teneurin-2 is a 2774 amino acid (aa) type II TM glycoprotein. It contains a 379 aa cytoplasmic region (aa 1-379) that contains a polySer segment (aa 331-334), plus a 2374 aa extracellular domain (ECD). The ECD possesses eight sequential EGF-like domains (aa 575-841), five NHL repeats, each of which forms a beta -propeller (aa 1272-1573), and 23 YD/TyrAsp-containing repeats that bind carbohydrates. There is a furin cleavage site after Arg528. There are three potential splice variants. One shows a deletion of aa 799-807, while two others show 46 and five aa substitutions for aa 1-167, respectively. Over aa 1-183, human teneurin-2 shares 98% aa identity with mouse teneurin-2.
