Scientific Data Images for Human Calsyntenin-1 Antibody

Detection of Human Calsyntenin-1 antibody by Western Blot.

Detection of Human Calsyntenin-1 by Western Blot.

Western blot shows lysates of human brain cortex and brain cerebellum tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Calsyntenin-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5346) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Calsyntenin-1 at approximately 115 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Calsyntenin-1

Calsyntenin-1 (CST-1; also Alcadein-alpha) is a 140‑150 kDa member of the Alcadein family of molecules. It is expressed in the ER/Golgi and on the plasma membranes of almost all neurons. It is a calcium-binding protein that may regulate post-synaptic signaling and APP cleavage and gene activation. Notably, when cleaved in a manner similar to APP, its intracellular fragment antagonizes APP AICD gene activation. Mature human CST-1 is a 953 amino acid (aa) type I transmembrane protein. It contains two cadherin domains (aa 38‑265) in its extracellular region (aa 29‑859) and a 101 aa cytoplasmic tail. Extracellular cleavage occurs at Met825 Ala826, generating a soluble 115 kDa ECD. Isoforms involve a 78 aa substitution for aa 917‑981, plus deletions of aa 72‑81 and 507‑525. Over aa 30‑851, human CST-1 shares 92% aa identity with mouse CST-1.
