PEP-131 is a 21 amino acid synthetic peptide whose sequences are derived from human nicastrin protein. The sequence of this peptide is (amino to carboxy terminus): C (688)-I-N-A-K-A-D-V-L-F-I-A-P-R-E-P-G-A-V-S-Y (708)
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human nicastrin, catalog # PA1-758. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~70-fold) for competitive inhibition of antibody-protein binding reactions.
Reconstitute with 0.1 mL of distilled water.
NCSTN (Nicastrin) is a gene that 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.
