背景信息

Nicalin (NCLN), a conserved endoplasmic reticulum (ER)-resident transmembrane protein, plays crucial roles in cellular homeostasis and developmental processes. It is a key component of the Nicastrin-Nicalin (NNC) complex, which associates with the γ-secretase complex involved in regulated intramembrane proteolysis (RIP) of substrates like Notch receptors and amyloid precursor protein (APP). Structurally, NCLN contains an N-terminal protease-like domain, a central lipid-binding domain, and a C-terminal transmembrane region. It exhibits chaperone-like activity, facilitating the proper folding and trafficking of membrane proteins.

Notably, NCLN regulates embryonic development by modulating Nodal/TGF-β signaling pathways. Studies link its dysfunction to congenital defects, including renal and cardiovascular malformations. Recombinant human NCLN protein, typically produced in mammalian or insect cell systems, retains post-translational modifications critical for its activity. This engineered protein enables in vitro studies of ER stress responses, protein-protein interactions, and substrate processing mechanisms. Recent structural analyses using recombinant NCLN have revealed its allosteric regulation of γ-secretase activity, offering insights into Alzheimer’s disease pathogenesis and potential therapeutic targeting. Current research also explores its role in cancer cell survival and chemotherapy resistance.
