Rabbit Monoclonal Antibody to Nicastrin

This gene encodes a type I transmembrane glycoprotein that is an integral component of the multimeric gamma~secretase complex. The encoded protein cleaves integral membrane proteins, including Notch receptors and beta~amyloid precursor protein, and may be a stabilizing cofactor required for gamma~secretase complex assembly. The cleavage of beta~amyloid precursor protein yields amyloid beta peptide, the main component of the neuritic plaque and the hallmark lesion in the brains of patients with Alzheimer's disease; however, the nature of the encoded protein's role in Alzheimer's disease is not known for certain. Mutations in this gene are associated with familial acne inversa. A pseudogene of this gene is present on chromosome 21. Alternatively spliced transcript variants of this gene have been described, but the full~length nature of some of these variants has not been determined. [provided by RefSeq, Feb 2014]
