Thus, in addition to the APP cleavage product Aβ, which influences synaptic transmission at the postsynapse, APP interacts with the calcium sensor of synaptic vesicles and might thus play a role in the regulation of synaptic vesicle exocytosis. Our results strongly argue for a function of APP in synaptic vesicle turnover in vivo. Among the candidate APP-interacting proteins, again only Stg1 was in close proximity to APP. Differentially tagged APPs showed clear sensitized FRET emission, in line with the described dimerization of APP.
We fused Citrine and Cerulean to APP and the candidate proteins and measured fluorescence resonance energy transfer (FRET) in differentiated SH-SY5Y cells. Your second brain needs a place to collect all the things that resonates with you, from an online article to your grocery list, through reliable tools like to-do list apps, web clipper, note-taking apps, and more. Synaptotagmin-1 (Stg1), a resident synaptic vesicle protein, was found to directly bind to APP. This concept is focused on behavior and habits first, rather than tools, and consists of 4 universal steps called CODE. We analyzed the interaction of APP with these proteins using pulldown experiments from transgenic mice or cotransfected cells followed by Western blotting. Confocal microscopy analyses of cotransfected primary neurons showed colocalization of APP with synaptic vesicle proteins in vesicular structures throughout the neurites. This enabled us to assess truly enriched proteins in the transgenic sample and yielded an overlapping set of proteins containing the major proteins involved in synaptic vesicle endo- and exocytosis. Using two different quantitative MS approaches, we compared the protein composition of affinity-purified samples isolated from wild-type mice versus transgenic mice expressing tagged APP. We used a proteomics-based approach by biochemically isolating tagged APP from the brains of transgenic mice and subjecting the affinity-purified complex to mass spectrometric (MS) analysis. Mind includes the following mental tests: CALCULATE: Squares will flash on a grid in succession, and all you need to do is keep track of the total.
To date, most proteins interacting with the APP intracellular domain (AICD) have been identified by Yeast Two Hybrid screens which only detect direct interaction partners.
