Gene Information from Publications

Publication Link Summary of findings
12297508 These data indicate that mammalian APH-1 (mAPH-1) along with presenilin 1 and nicastrin is probably a functional component of the gamma-secretase complex required for the intramembrane proteolysis of APP and Notch
12972157 Six different polymorphisms have been determined but the polymorphisms in APH-1a/b coding regions are not linked to higher risk for Alzheimer disease in an Italian population.
14593096 APH-1 can be processed by several endoproteolytic events and generates a stable C-terminal fragment that associates with nicastrin
15210705 Only the combined overexpression of presenilin 1 and nicastrin together with APH-1a G122D facilitated the formation of a fully active gamma-secretase complex
17059559 Over-expression of APH-1 and inhibition of proteasomal APH-1 degradation facilitated gamma-secretase cleavage of APP to generate Abeta. Thus,degradation of APH-1 protein is mediated by the ubiquitin-proteasome pathway.
12471034 APH-1 binds to presenilins and nicastrin and may play a role in maturation of presenilin-nicastrin complexes
12917438 APH-1 and the gamma-secretase complex bind to the transmembrane domain region of nicastrin
15629423 knock down of APH-1a, but not APH-1b, resulted in impaired maturation of nicastrin and reduced expression of presenilin 1, presenilin 2, and PEN-2 proteins
16757808 These results collectively indicate that the three forms of APH-1 can replace each other in presenilin (PS) complexes and that the transmembrane GxxxG region is essential for the stability of the APH-1 protein as well as the assembly of PS complexes.
12763021 Expression of APH-1A increases amyloid beta peptide levels and gamma-secretase activity.
