| 1351739 | NCSTN | 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-se cretase 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.

| 1551174 | Ncstn | nicastrin | Contributes to aspartic endopeptidase activity, intramembrane cleaving. Acts upstream of or within several processes, including amyloid precursor protein metabolic process; positive regulation of amyloid precursor protein biosynthetic process; and regulation of synaptic plasticity. Located in severa l cellular components, including Golgi apparatus; lysosome; and synaptic vesicle. Part of gamma-secretase complex. Is expressed in several structures, including brain and genitourinary system. Used to study chronic myeloid leukemia; schizophrenia; and urinary bladder cancer. Human ortholog(s) of this gene implicated in Alzheimer's disease; hidradenitis suppurativa; and schizophrenia. Orthologous to human NCSTN (nicastrin).
