Function

edit

Nicastrin (abbreviated NCT) is aproteinthat is part of thegamma secretaseprotein complex,which is one of theproteasesinvolved in processingamyloid precursor protein(APP) to the shortAlzheimer's disease-associated peptideamyloid beta.The other proteins in the complex arePSEN1(presenilin-1), which is thecatalyticallyactive component of the complex,APH-1(anterior pharynx-defective 1), andPEN-2(presenilin enhancer 2).[8]Nicastrin itself is not catalytically active, but instead promotes the maturation and proper trafficking of the other proteins in the complex, all of which undergo significantpost-translational modificationbefore becoming active in the cell.[9]Nicastrin has also been identified as a regulator ofneprilysin,anenzymeinvolved in the degradation of amyloid beta fragment.[10]

History

edit

The protein was named after the Italian countryNicastro,reflecting the fact that Alzheimer's disease was described in 1963 after studying descendants of an extended family originating in the country of Nicastro that hadfamilial Alzheimer's disease(FAD).[11]

Interactions

edit

Nicastrin has been shown tointeractwithPSEN1[12][13][14][15][16]andPSEN2.[12][16]
