Scientific Data Images for Human Nicastrin Antibody
Detection of Human Nicastrin by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and A549 human lung carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Nicastrin Monoclonal Antibody (Catalog # MAB53781) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for Nicastrin at approximately 110-120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human Nicastrin Antibody

Background: Nicastrin
Nicastrin (NCT) is a 150‑160 kDa member of the nicastrin family of proteins. It is a component of the aspartyl protease gamma-secretase complex and serves to stabilize and direct gamma-secretase components to proper positions in the plasma membrane. The gamma-secretase complex mediates the cleavage of intramembrane proteins such as notch-1 and APP. Mature human nicastrin is a 676 amino acid type I transmembrane glycoprotein. It contains a 636 aa extracellular domain (aa 34‑669) that shows a 58 aa sequence (aa 312‑369) which interacts with gamma-secretase substrates. There are multiple splice variants of NCT. One shows a deletion of aa 195‑322 and 394‑709, a second shows a 29 aa substitution for the C-terminal 604 aa and a third shows a deletion of aa 200‑709 accompanied by an insertion of 33 aa after Leu30. Over aa 34‑669, human NCT shares 90% aa identity with mouse NCT.
