Splet02. apr. 2024 · APP Trafficking and Post-Translational Modifications (PTMs) After its synthesis, APP is firstly translocated to the Endoplasmic Reticulum (ER) upon the removal of its SP sequence, then it transits the ER/ER-Golgi Intermediate Compartment (ERGIC) to locate into the Golgi apparatus and the Trans-Golgi Network (TGN). SpletIn this chapter we describe the cell biological and biochemical characteristics of the three secretase activities involved in the proteolytic processing of the precursor protein. In …
Splet23. maj 2012 · In the amyloidogenic pathway, amyloid precursor protein (APP) undergoes sequential steps of proteolytic processing, first by the β-site APP cleaving enzyme (BACE), and then by γ-secretase to generate Aβ peptides. ... Furthermore, we noted distinct effects on APP processing and trafficking upon depletion of subunits of different ESCRT ... SpletHere, we highlight recent research on intracellular trafficking/sorting of APP and BACE‐1, and discuss how dysregulation of these pathways might …
Splet13. jan. 2024 · The distribution of amyloid beta peptide 42 (Aβ42) between model exosomal membranes and a buffer solution was measured. The model membranes contained liquid-ordered regions or phosphatidylserine. Results demonstrated that up to ca. 20% of amyloid peptide, generated in the plasma (or intracellular) membrane as a result … SpletMounting evidence has demonstrated that alterations in APP cellular trafficking and localization directly impact its processing to Abeta. Members of the low-density …
SpletDISC1 is a risk factor for a wide variety of psychiatric disorders. 7,8 We previously published binding of APP to DISC1, through the C-terminal intracellular domain of APP. 9 A major unanswered question is whether this interaction modulates the proteolytic processing of APP and the generation of Aβ peptides. In the present exploratory study ...
