Calsyntenin-2 Antibody

Calsyntenin‑2 was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Sheep Anti-Human Calsyntenin‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5480) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to neurons.

Background

Calsyntenin-2 (CS-2) is a 120-135 kDa member of the Alcadein family of molecules. It is expressed in the ER/Golgi, and the plasma membranes of almost all neurons. It is a calcium-binding protein that interacts with APP and X11L. In this regard, it appears to regulate APP cleavage and gene activation, and likely impacts post-synaptic signaling. Notably, when cleaved in a manner similar to APP, its intracellular fragment antagonizes AICD gene activation. Mature human CS-2 is a 935 amino acid (aa) type I transmembrane protein. It contains two cadherin domains (aa 44-280) in its extracellular region (aa 21-831) and a 103 aa cytoplasmic tail. Proteolytic cleavage by ADAM10 occurs between His803 and Leu804 to generate a 105-110 kDa extracellular fragment. Additional processing of the transmembrane fragment by gamma -secretase creates a 3 kDa fragment (aa 804-834) plus a 25 kDa cytoplasmic protein. Potential isoform variants show a premature truncation after Gln608, and the use of an alternative start site at Met409. Over aa 21-834, human CS-2 shares 95% aa identity with mouse CS-2.
